For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] As mentioned in the background art, when the number of tab layers changes, the smoothing plate in the prior art is prone to not being smoothed properly, tabs being folded, or tabs being scratched. In order to improve the above situation, the present application provides a tab smoothing device and a winding machine, which can adjust the gap between the tab and the smoothing plate to avoid the tab tearing problem due to insufficient space.
[0029] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a tab smoothing device 10 provided in an embodiment of the utility model. Figure 2 Another schematic diagram of the tab smoothing device 10 provided in the embodiment of the utility model. The present application provides a tab smoothing device 10, which includes a fixing frame 100, a power cylinder 200, a connecting frame 300 and an elastic smoothing plate 400.
[0030] Among them, the fixing frame 100 is connected to the shell of the power cylinder 200 and is used to be set at one end of the reel 30; one end of the connecting frame 300 is connected to the output shaft of the power cylinder 200, and the other end extends to the side of the reel 30 and is connected to the elastic smoothing plate 400; the elastic smoothing plate 400 is bent toward the reel 30; the power cylinder 200 is used to drive the connecting frame 300 to rise and fall, so that the elastic smoothing plate 400 and the reel 30 are separated by a preset gap.
[0031] Based on the above configuration, it can be understood that when the tab passes through the preset gap between the elastic smoothing plate 400 and the reel 30, it can be smoothed by the elastic smoothing plate 400 without folding, wrinkling, flanging, bending to varying degrees, etc. Moreover, when the number of layers of the tab changes, the power cylinder 200 can drive the elastic smoothing plate 400 to move by driving the connecting frame 300 to ensure that the preset gap is always maintained between the elastic smoothing plate 400 and the reel 30 wound with the tab, thereby ensuring that the tab is smoothly smoothed.
[0032] Considering that the preset gap must be within a reasonable range, the preset gap ranges from 0 to 2 mm. Based on this, on the one hand, it is avoided that the tab is difficult to be smoothed by the elastic smoothing plate 400 due to the preset gap being too large, and on the other hand, it is avoided that the tab is torn or difficult to pass due to the preset gap being too small.
[0033] In addition, considering that silicone material has good softness and elasticity, the elastic smoothing plate 400 is made of silicone material so that it can be adaptively bent to the required curvature to ensure that the contact area with the surface of the tab is maximized and the smoothing work is performed more effectively.
[0034] Please refer again Figure 2The tab smoothing device 10 further includes a detection probe 410, which is disposed on the elastic smoothing plate 400 and is used to obtain the spacing information between the elastic smoothing plate 400 and the reel 30. Through the above arrangement, the spacing between the elastic smoothing plate 400 and the reel 30 can be obtained in real time, and can be adjusted in real time to ensure that the spacing is always within the preset spacing range.
[0035] Further, considering that the elastic caressing plate 400 has a curvature, the number of the detection probes 410 is three, and the three detection probes 410 are respectively arranged at the two ends and the middle of the elastic caressing plate 400. It is understandable that the staff can judge the overall position of the elastic caressing plate 400 by judging the positions of the middle and the two ends of the elastic caressing plate 400. Optionally, the three detection probes 410 are arranged at intervals on the same curve.
[0036] Please refer again Figure 1 The connecting frame 300 includes a connecting member 310, a first connecting rod 330 and a second connecting rod 350; one end of the connecting member 310 is sequentially penetrated by the first connecting rod 330 and the second connecting rod 350, and the other end is connected to the output shaft of the power cylinder 200; the first connecting rod 330 and the second connecting rod 350 are respectively connected to the two ends of the elastic smoothing plate 400, so that the elastic smoothing plate 400 is bent into a preset angle.
[0037] Based on the above arrangement, it can be understood that the first connecting rod 330 and the second connecting rod 350 are respectively pressed against the two ends of the elastic smoothing plate 400, so that the elastic smoothing plate 400 is bent into a preset angle, so that the pole piece passing through the reel 30 is bent into a preset angle to achieve the smoothing of the pole ear. It should be noted that the preset angle specifically refers to the angle adapted to the reel 30, that is, the angle adapted to the pole piece running direction.
[0038] Furthermore, the first connecting rod 330 and the second connecting rod 350 can both rotate relative to the connecting member 310, so as to adaptively adjust the elastic smoothing plate 400 to a preset angle. Specifically, the staff can adjust the preset angle of the elastic smoothing plate 400 by adjusting the first connecting rod 330 and the second connecting rod 350 to be suitable for reels 30 of different diameters. It should be noted that the staff can obtain the corresponding reel 30 information through the detection probe 410.
[0039] Furthermore, if Figure 1 As shown, the first connecting rod 330 and the second connecting rod 350 are cross-arranged at one end of the connecting member 310. It is understandable that, since the diagonal angle at the intersection is always consistent, the staff can adjust the elastic smoothing plate 400 to a preset angle by adjusting the first connecting rod 330 and the second connecting rod 350 away from one end of the elastic smoothing plate 400.
[0040] Specifically, to facilitate automatic adjustment of the curvature, the connecting frame 300 further includes an adjusting member 370, one end of which is connected to an end of the first connecting rod 330 away from the elastic smoothing plate, and the other end of which is connected to an end of the second connecting rod 350 away from the elastic smoothing plate.
[0041] It is understandable that the adjusting member 370 may be a double-rod hydraulic cylinder, and the two output rods are respectively connected to the first connecting rod 330 and the second connecting rod 350 to synchronously drive the first connecting rod 330 and the second connecting rod 350 to extend and retract. Alternatively, the adjusting member 370 may be a single-rod hydraulic cylinder, and the housing is connected to the first connecting rod 330, and the output shaft is connected to the second connecting rod 350. In addition, it should be noted that the positional relationship between the adjusting member 370, the connecting member 310 and the elastic smoothing plate 400 may be adaptively adjusted by using the lever principle.
[0042] It should be noted that the tab smoothing device 10 may include two power cylinders 200, two connecting frames 300 and two elastic smoothing plates 400. The specific connection method of the above elements is as above, and the two elastic smoothing plates 400 are arranged at intervals along the wiring direction of the pole piece to ensure that the tab will not be deflected during feeding and discharging.
[0043] In addition, it should be noted that the power cylinder 200, the detection probe 410 and the adjustment member 370 can be connected to the central control device for communication so as to realize automatic adjustment. Based on this, the central control device integrated with the automation system and the intelligent control system can monitor or adjust in real time to avoid manual adjustment of the tab smoothing device after changing the type and material.
[0044] Taking this embodiment as an example, the specific working principle and working process of the tab smoothing device 10 are as follows:
[0045] The detection probe 410 obtains the distance between the elastic smoothing plate 400 and the reel 30, and simultaneously obtains the diameter of the reel 30, and transmits it to the central control device. Afterwards, the power cylinder 200 that receives the central control command is telescopically adjusted to make the distance between the elastic smoothing plate 400 and the reel 30 a preset gap; the adjustment member 370 that receives the central control command is telescopically adjusted to bend the elastic smoothing plate 400 to a preset angle. After the adjustment is completed, when the pole piece drives the pole ear to pass through the preset gap between the elastic smoothing plate 400 and the reel 30, the pole ear can be smoothed by the elastic smoothing plate 400. In addition, it should be noted that during the smoothing process, the detection probe 410 always obtains the spacing information and adaptively adjusts the power cylinder 200 to ensure that the preset gap is always maintained between the elastic smoothing plate 400 and the reel 30 wound with the pole ear.
[0046] In summary, the present application provides a tab smoothing device 10, which includes a fixing frame 100, a power cylinder 200, a connecting frame 300, and an elastic smoothing plate 400. It is understandable that when the tab passes through the preset gap between the elastic smoothing plate 400 and the reel 30, it can be smoothed by the elastic smoothing plate 400 without folding, wrinkling, flanging, bending to varying degrees, and other problems. In addition, when the number of layers of the tab changes, the power cylinder 200 can drive the connecting frame 300 to move, so as to drive the elastic smoothing plate 400 to move, thereby ensuring that the preset gap is always maintained between the elastic smoothing plate 400 and the reel 30 wound with the tab, thereby ensuring that the tab is smoothly smoothed.
[0047] In addition, the present application also provides a winding machine, which includes a tab smoothing device 10 and a reel 30, so it can also adjust the gap between the tab and the smoothing plate to avoid the tab tearing problem caused by insufficient space.
[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
