Description

Technical Field

[0001] This application relates to the field of coating machines, and in particular to a cooling and wrinkle-removing assembly for the outlet of a coating machine oven. Background Technology

[0002] In battery manufacturing, processed electrode sheets need to be conveyed to a coating machine. After coating, multiple take-up rollers are mounted on the frame to achieve the winding action. During the conveying process, the sheet passes through numerous take-up rollers. The conveying path is long and winding, making it susceptible to various factors such as insufficient pressure on the take-up rollers, unbalanced tension control, and wrinkles during the journey, which can lead to abnormal winding. These problems prevent the coated parts from maintaining a parallel state or being stacked at uniform intervals, ultimately resulting in interlayer wrinkles, misalignment, or uneven spacing during winding. This not only causes poor overall flatness of the coated parts after winding but also directly affects the final coating quality and subsequent processing. Utility Model Content

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0017] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0018] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0019] The following is combined Figures 1 to 5 The embodiments of this utility model are described below.

[0020] This application provides a cooling and wrinkle removal assembly for the outlet of a coating machine oven, which includes a frame 100 and a wrinkle removal mechanism 200, a cooling mechanism 300 and a pressing mechanism 400 arranged sequentially along the winding direction and disposed on the frame 100. The wrinkle removal mechanism 200 includes an extension roller 210 with an outward diffusion structure. The extension roller 210 is rotatably connected to the frame 100 and is used to extend the coated part outward to prevent wrinkles from being carried into subsequent processes.

[0021] The cooling mechanism 300 includes a blower for blowing air onto the coated part as it passes, ensuring that the coated part is fully dry.

[0022] The outlet of the coating machine oven is set to correspond to the feed end of the winding assembly. When the coated part is fed in, it first passes through the stretching roller 210 of the wrinkle removal mechanism 200. The diffusion structure on the roller unfolds the wrinkles of the coated part in frictional contact. The flattened coated part enters the cooling mechanism 300. The airflow from the blower blows the coated part to achieve cooling.

[0023] Optionally, a clamping mechanism 400 is also included, which includes a swaying clamping roller 440 for clamping the coated part before winding. Subsequently, when the coated part reaches the clamping mechanism 400, the swaying clamping roller 440 is driven to press against the roll on the winding shaft, applying pressure to the passing coated part to ensure tight and neat winding.

[0024] Therefore, by providing a wrinkle-removing mechanism 200, a cooling mechanism 300, and a pressing mechanism 400, the coated part passes through the wrinkle-removing mechanism 200, the cooling mechanism 300, and the pressing mechanism 400 in sequence. Before winding, the wrinkles of the coated part are reduced in advance, and the cooling effect on the electrode sheet is improved. Then, the coated part is pressed to avoid the loose gap of the roll body being too large, thereby improving the flatness of the winding and thus helping to improve the winding quality.

[0025] In some embodiments, the diffusion structure is a diffusion thread 211 that extends outward from the center to both ends, causing the coating to extend outward. The coating is fed in along the winding direction and, after contacting the stretching roller 210, the stretching roller 210 rotates on the frame 100. Along the traveling direction of the coating, since the diffusion thread 211 extends outward from the center to both sides, the diffusion thread 211 on its surface rubs against the coating, causing the coating to be stretched laterally on both sides when the roller rotates, so that the coating can achieve lateral extension, effectively reducing wrinkles as the coating enters the subsequent winding stage, and improving the flatness of the final wound product.

[0026] Because the traveling coating component easily generates negative air pressure with the roller surface, leading to adhesion, in some embodiments, the stretching roller 210 is provided with an stretching groove 212, which is arranged along the extension path of the diffusion thread 211. As the coating component moves along the roller body on the stretching roller 210, the stretching groove 212 provides an airflow channel between the coating component and the roller surface, thereby preventing negative pressure from forming between the coating component and the stretching roller 210, and thus avoiding adhesion of the coating component to the stretching roller 210. This reduces the risk of conveying jams or positional shifts caused by the coating component adhering to the stretching roller 210, ensuring smooth conveying of the coating component.

[0027] In some embodiments, the wrinkle removal mechanism 200 further includes a height adjustment component 220, which is disposed on the frame 100. The stretching roller 210 is connected to the frame 100 through the height adjustment component 220 so that the height of the stretching roller 210 can be adjusted by the height adjustment component 220.

[0028] Optionally, the height adjustment assembly 220 includes multiple pairs of drive devices and sliders. Each end of the stretching roller 210 is connected to one of the sliders. The drive devices are fixed to the frame 100, and each slider is fixed to the output shaft of the drive device. The drive device can be a cylinder, a threaded rod, or a motor, allowing selection of the appropriate drive device based on the thickness of the workpiece to be coated. When a cylinder is selected, its output shaft extends and retracts, moving the slider. When a threaded rod is used, turning the threaded rod drives the slider up and down. The slider movement synchronously raises and lowers the stretching roller 210 until it is adjusted to a height matching the thickness of the workpiece. This improves the adaptability of the coating machine to workpieces of different thicknesses, eliminating the need for frequent replacement of the stretching roller 210 for different workpieces.

[0029] In some embodiments, the cooling mechanism 300 includes at least two air blowers, each fixed to the frame 100. Each air blower has an air collecting chamber with an interconnected air inlet and outlet. The air inlet connects to the outlet of a fan, and the outlet blows air outwards to dry the coated workpiece. Thus, the cooling mechanism 300 has at least two air blowers fixed to the frame 100, each with an air collecting chamber. The fan outlet is connected to the air inlet of the air blower. When the fan is started, airflow enters the air collecting chamber and converges within it, then is blown out through the outlet onto the coated workpiece, thereby utilizing the airflow to dry and cool the coated workpiece.

[0030] In some embodiments, the two air blowers are an upper air blower 310 and a lower air blower 320, which are arranged opposite to each other. The upper air blower 310 is provided with a first air outlet 312, and the lower air blower 320 is provided with a second air outlet 322. Both the first air outlet 312 and the second air outlet 322 are arranged laterally to blow air laterally. The coated part passes between the upper air blower 310 and the lower air blower 322 along the winding direction. The fan supplies air to the two air blowers, and the airflow is blown out from the first air outlet 312 and the second air outlet 322, respectively, acting on the surface of the coated part from both the top and bottom sides, continuously drying the coated part. In this way, the horizontally arranged air outlet has a larger blowing area and a longer effect than the vertically arranged air outlet, further improving the drying effect.

[0031] In some embodiments, the upper blower 310 is provided with an upper air outlet 311 along its length, and the lower blower 320 is provided with a lower air outlet 321 along its length. A first air outlet 312 is provided on the upper air outlet 311, and a second air outlet 322 is provided on the lower air outlet 321. The upper air outlet 311 and the lower air outlet 321 are arranged parallel to each other. Because it is a wide-width coated part, the coated part passes between the relatively arranged upper air duct 310 and lower air duct 320. When the coated part is a wide-width coated part, after entering the cooling mechanism 300, it passes between the upper and lower air outlet ducts 321. The airflow delivered by the fan enters the upper air outlet duct 311 through the upper air duct 310 and is blown out from the first air outlet 312. At the same time, it enters the lower air outlet duct 321 through the lower air duct 320 and is blown out from the second air outlet 322. The airflow acts on the coated part along its full width, sweeping the entire surface of the coated part. This avoids the edges of the coated part not being able to contact the airflow, which would affect the drying effect, and ensures that the wide-width coated part is covered by the airflow along its width.

[0032] Optionally, both the upper air outlet duct 311 and the lower air outlet duct 321 are flat slit structures with a cross-section resembling a duckbill. After the air blower is installed, there is a small angle between the cooling air outlet and the incoming electrode, thereby increasing the contact area between the blown air and the electrode and significantly improving the cooling effect on the electrode.

[0033] In some embodiments, the pressing mechanism 400 further includes a drive member 410, a rotating shaft 420, and a swing arm 430. The drive member 410 is mounted on the frame 100 and is connected to the rotating shaft 420 to drive the rotating shaft 420 to swing. One end of the swing arm 430 is connected to the rotating shaft 420, and the other end is equipped with a pressing roller 440. When the coated part is about to enter the winding stage, the drive member 410 drives the rotating shaft 420 to rotate. Since the swing arm 430 is fixedly connected to the rotating shaft 420, the rotation of the rotating shaft 420 drives the swing arm 430 to swing. The swing arm 430 drives the pressing roller 440 to move towards the coated part until the pressing roller 440 is in close contact with the surface of the coated part, applying stable pressure to the coated part and making the coated part roll more compact. Thus, the drive unit 410, fixed on the frame 100, drives the rotating shaft 420 to rotate, and the swing arm 430, fixed to the rotating shaft 420, rotates synchronously with the shaft, thereby driving the pressure roller 440, fixed on the swing arm 430, to move, thereby achieving the pressing of the coated part before winding. Optionally, the drive unit 410 can be a cylinder or a motor.
