Description

Technical Field

[0001] The utility model belongs to the technical field of composite collector processing, and particularly relates to a composite collector rewinding and rolling integrated machine. Background Art

[0002] At present, during the production process of composite collectors, it is found that there are convex points on the surface of the processed composite collectors. However, in the subsequent coating process of the composite collectors, the height of the areas with convex points on the surface is higher than the height of the coating section in the coating equipment. When forced to pass through the coating section, the areas with convex points on the composite collector are easily broken, resulting in the tearing of the composite collector and causing product quality problems. Therefore, a composite collector rewinding and rolling integrated machine is designed to solve the above problems.

[0003] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the utility model. Summary of the Utility Model

[0004] To overcome the deficiencies in the above-mentioned prior art, the purpose of the utility model is to provide a composite collector rewinding and rolling integrated machine.

[0005] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a composite collector rewinding and rolling integrated machine, which is sequentially provided with a unwind mechanism, a first flattening roller, a rolling mechanism, a second flattening roller, and a winding mechanism along the direction of the composite collector film; the rolling mechanism includes an upper roller and a lower roller, and at least one of the upper roller and the lower roller is adjustable up and down; when the upper roller and the lower roller are pressed together, the upper roller and the lower roller can be respectively pressed against the upper surface and the lower surface of the film. In this solution, the composite collector film is rewound through the flattening roller, improving the flatness of the film. During the rewinding process, it is also subjected to rolling treatment by the rolling mechanism to roll the convex points on the film surface, making the convex points lower or disappear, preventing the composite collector from being damaged during coating, and improving product quality.

[0006] Further, the angle formed when the film winds around the first flattening roller and the second flattening roller is greater than 90° and less than 130°. In this solution, when the angle formed when the film winds around the first flattening roller and the second flattening roller is an obtuse angle, the composite collector film can be more closely attached to the flattening roller.

[0007] Further, it further includes a detection mechanism located behind the second flattening roller. The detection mechanism includes a conveying roller for supporting the film and a scraper located above the conveying roller. A gap is provided between the scraper and the conveying roller, and the gap is between the single film thickness and twice the film thickness. In this solution, the scraper of the detection mechanism can detect the rolled film, and the height of the bumps on the film can be detected through the gap. If the bumps after rolling are not high, it meets the passing condition and can pass; otherwise, if the bumps after rolling are high, it does not meet the passing condition, and it may tear the film during coating and cannot pass. By detecting the height of the bumps on the film, the quality of the rolled film is controlled, and the product quality is further ensured.

[0008] Further, the length of the scraper along the axial direction of the conveying roller is greater than or equal to the length of the conveying roller. In this solution, setting the length of the scraper to be not less than the length of the conveying roller can ensure that the entire width direction of the film can pass through the scraper for detection, ensuring that the detection is in place.

[0009] Further, a blowing mechanism is provided between the second flattening roller and the detection mechanism, and the blowing mechanism is located above the film. In this solution, before detecting the height of the film, blowing air on its upper surface can play a role in cooling and dust removal, making the detection effect more accurate.

[0010] Further, a first dust sticking roller, a second dust sticking roller and a guiding roller are sequentially arranged behind the detection mechanism along the direction of the composite current collector film. The first dust sticking roller and the second dust sticking roller are respectively located on different sides of the film. In this solution, the first dust sticking roller and the second dust sticking roller respectively perform dust sticking treatment on both sides of the film, keeping the two surfaces of the composite current collector film clean and improving the product quality.

[0011] Further, a first CCD detection unit is provided on one side of the first dust sticking roller, a second CCD detection unit is provided on one side of the second dust sticking roller, the first CCD detection unit and the second CCD detection unit are respectively located on different sides of the film, and a third CCD detection unit is provided on one side of the guiding roller. In this solution, the first CCD detection unit and the second CCD detection unit respectively detect the cleanliness of both sides of the film, evaluate the product quality, and ensure the product quality; the third CCD detection unit is used for comprehensive detection and evaluation of defects such as pinholes, dust, and dirt on the film surface to ensure the product quality.

[0012] Further, a heating mechanism is provided between the first flattening roller and the rolling mechanism. The heating mechanism includes a first heating element for heating the upper surface of the film and a second heating element for heating the lower surface of the film. In this solution, before rolling the film of the composite current collector, it is first heated by the heating mechanism, which can make the bumps on the film surface easier to be rolled flat.

[0013] Further, the heating mechanism is provided with a temperature control system. In this solution, setting the temperature control system can monitor and control the heating temperature, control the heating problem within a suitable range, and avoid affecting the film quality due to excessive temperature.

[0014] Further, a plurality of guide rollers are also provided between the unwinding mechanism and the winding mechanism. In this solution, setting a plurality of guide rollers is used to guide the film in multiple directions, which is convenient for the overall layout.

[0015] Due to the application of the above technical solution, the beneficial effects of the present utility model compared with the prior art are:

[0016] The rewinding and rolling integrated machine for composite current collectors designed by the present utility model rewinds the film of the composite current collector through the flattening roller, improving the flatness of the film. During the rewinding process, it is also rolled through the rolling mechanism to roll the bumps on the film surface, making the bumps lower or disappear, preventing the composite current collector from being damaged during coating, and improving the product quality; and by setting the detection mechanism to detect the height of the film bumps, the quality of the film after rolling is controlled, further ensuring the product quality.
