Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to an automatic correction device for lithium battery winding. Background Technology

[0002] Lithium-ion batteries use lithium-containing active materials as electrodes and are a typical example of modern high-performance battery technology. Currently, lithium-ion batteries are widely used in various power tools and other large, medium, and small electric equipment. With the continuous advancement of electrical equipment technology, the performance requirements for lithium-ion batteries are also increasing. In the lithium battery production process, the electrode winding process requires a belt-carrying operation on a winding machine. Given the tendency for deviation to occur during belt-carrying, the unwinding and rewinding ends of the winding machine must be equipped with deviation correction devices to ensure the stability of the belt-carrying process.

[0003] However, existing correction devices have revealed certain technical shortcomings in practical applications. Although these devices can complete basic correction operations, they lack an effective detection mechanism to verify the accuracy of the correction after completion. Furthermore, they cannot achieve dynamic correction adjustment, making it difficult to ensure the precision and accuracy of correction adjustment, thus affecting quality control and production efficiency in the lithium-ion battery production process. Utility Model Content

[0004] The purpose of this invention is to provide an automatic correction device for lithium battery winding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic correction device for lithium battery winding, comprising a base plate, a moving mechanism equidistantly arranged on the base plate, an adjusting mechanism arranged on the moving mechanism, a correction roller arranged between two adjusting mechanisms on the same moving mechanism, a detection component arranged on the base plate, the correction roller and the detection component being staggered, and a limiting component arranged on the base plate.

[0006] Preferably, in order to facilitate the movement of the correction roller and make it convenient to perform correction operations as needed, the moving mechanism includes an adjustment groove on the base plate, an adjustment block is slidably provided in the adjustment groove, and a screw is rotatably provided in the adjustment groove. One end of the screw is fixedly connected to the output end of the motor. The adjustment block engages with the screw through a thread, and a moving plate is fixedly provided on the adjustment block.

[0007] Preferably, in order to facilitate the adjustment of the height of the correction roller, make it easy to make adaptive adjustments, and also adjust the tension during the conveying process, the adjustment mechanism includes a chute opened in the middle of the moving plate, a slider is slidably arranged in the chute, a correction roller is rotatably arranged between two sliders, and an electric push rod is provided at the top of the moving plate, with the output end of the electric push rod fixedly connected to the slider.

[0008] Preferably, in order to ensure stability during the adjustment and movement process, the two side walls of the slider are symmetrically provided with limiting guide blocks, and the slide groove is provided with a limiting guide groove that matches the limiting guide blocks.

[0009] Preferably, in order to perform inspection after the correction is completed, the correction roller and the moving mechanism are dynamically adjusted to ensure the correction effect. The inspection component includes a mounting frame set on the base plate. A laser emitter is provided at the top of the mounting frame, and a laser receiver matching the laser emitter is provided at the bottom of the mounting frame.

[0010] Preferably, in order to guide and limit the conveyor belt after correction and prevent it from deviating again, the limiting component includes mounting frames symmetrically arranged on the base plate, with guide and limiting rollers equidistantly arranged between the two mounting frames.

[0011] Preferably, the guide and limiting roller is also provided with limiting rings symmetrically on its peripheral side.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The equipped detection component, through the cooperation of a laser emitter and a laser receiver, can detect the position of the material strip after the correction is completed. During the correction adjustment process, if both sets of laser receivers can receive signals, it indicates that the correction is complete; if one set does not receive a signal, it means that the correction is not complete. At this time, the correction can be readjusted again through the subsequent moving mechanism. This detection and dynamic adjustment mechanism ensures the accuracy of the correction effect, avoids the problem of material strip deviation caused by incomplete correction, and improves product quality. The setting of the limiting component provides reliable guidance and limiting for the conveying of the material belt after correction. The guide limiting rollers are symmetrically arranged between the mounting brackets on the base plate at equal intervals, and the peripheral side of the guide limiting rollers is also symmetrically provided with limiting rings, which can limit and guide the two ends of the conveying material belt to prevent the material belt from deviating again during the conveying process. At the same time, the limiting component, the moving mechanism, the adjusting mechanism and the detection component work together to form a complete correction and conveying system, which further enhances the stability and reliability of the material belt conveying.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Please see Figures 1-5 This utility model provides an embodiment of an automatic lithium battery winding correction device, comprising a base plate 11, on which a moving mechanism is equidistantly arranged. A correction roller 12 is mounted on the moving mechanism via an adjusting mechanism to facilitate adjustment and correction of the conveyed lithium battery strip, preventing deviation. A detection component is also provided on the base plate 11. The correction roller 12 and the detection component are staggered, allowing for detection after correction to ensure the effectiveness of the correction and prevent deviation. A limiting component is also provided on the base plate 11 for convenient guiding and limiting after correction. The limiting component includes symmetrically arranged components. On the base plate 11, there are mounting brackets 31, and guide limiting rollers 32 are provided at equal intervals between the two mounting brackets 31. For the two limiting rollers, a height adjustment device can be provided between them and the mounting brackets 31. The specific structure can be the same as the adjustment mechanism, or other methods can be used for adjustment. The gap between the two guide limiting rollers 32 can be adjusted to adapt to material belts of different thicknesses. The circumferential side of the guide limiting rollers 32 is also symmetrically provided with limiting rings 33. The limiting rings 33 can be made of elastic materials, such as rubber, to facilitate limiting and guiding the two ends of the conveyor belt and prevent deviation.

[0017] Please see Figures 1-5To facilitate adjustment and correction of the conveyor belt without affecting subsequent use, the moving mechanism includes an adjustment groove 22 on the base plate 11. An adjustment block 24 is slidably disposed within the adjustment groove 22. A screw 23 is rotatably disposed within the adjustment groove 22. One end of the screw 23 is fixedly connected to the output end of the motor 21 via a coupling. The adjustment block 24 engages with the screw 23 via threads. A moving plate 41 is fixedly disposed on the adjustment block 24. When the motor 21 operates, it rotates the screw 23. Furthermore, under the action of threaded engagement, the adjusting block 24 can move within the adjusting groove 22, the two moving plates 41 can be moved and adjusted, the correcting roller 12 can be moved laterally, and the material belt can be moved to perform correction operations. In order to facilitate the adjustment of the height of the correcting roller 12 for convenient conveying and guidance, and also to adjust the tension, the adjusting mechanism includes a slide groove 44 opened in the middle of the moving plate 41, a slider 43 slidably arranged in the slide groove 44, and the correcting roller 12 rotatably arranged between the two sliders 43. An electric push rod 4 is provided at the top of the moving plate 41. 2. The output end of the electric push rod 42 is fixedly connected to the slider 43. The two side walls of the slider 43 are symmetrically provided with limiting guide blocks 46. The slide groove 44 is provided with a limiting guide groove 45 that matches the limiting guide block 46. This can ensure the stability of the movement during the up and down adjustment process and avoid the situation of deviation. In order to facilitate the detection of the material strip after correction and avoid the situation of deviation, the detection component includes a mounting frame 13 set on the base plate 11. The mounting frame 13 and the base plate 11 can be connected by a moving device to facilitate the adjustment of the position of the mounting frame 13 according to the width of the material strip. This ensures that the distance between the two laser emitters 14 is equivalent to the width of the material strip. After the correction is completed, the two sets of laser emitters 14 work. The two sets of laser receivers 15 at the bottom can receive the signal, which means that the correction is completed. If one set does not receive the signal, it means that the correction is not completed. The correction can be adjusted again by the next set. The top of the mounting frame 13 is provided with a laser emitter 14, and the bottom of the mounting frame 13 is provided with a laser receiver 15 that matches the laser emitter 14.

[0018] Working principle: In use, the electric push rod 42 extends and retracts, allowing the slider 43 to slide within the groove 44. The limiting guide block 46 slides within the limiting groove 44, ensuring stability during vertical movement and adjustment. This allows for adjustment of the height of the correction roller 12, enabling adaptive adjustments and adjusting the tension of the conveyor belt. During conveying, the laser emitter 14 operates, and the laser receiver 15 receives a signal, indicating no deviation. Subsequent conveying is then achieved through the guide limiting roller 32 and the limiting ring 33, avoiding... To prevent deviation, when deviation occurs and correction is needed, the motor 21 rotates, which in turn rotates the screw 23, causing the adjusting block 24 to move back and forth within the adjusting groove 22. This, in turn, causes the moving plate 41 and the correction roller 12 to move laterally, thus moving the material belt laterally for correction. When the laser emitter 14 is working and the laser receiver 15 receives a signal, it indicates that the correction is complete. The motor 21 then stops rotating, and subsequent conveying work can proceed. With the help of the guide limit roller 32 and the limit ring 33, the conveying can be limited to prevent deviation from occurring again.

[0019] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
