Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the lithium-ion electrolytic copper foil forming all-in-one machine comprises a frame 1, a guide roller 2, a tension roller 3, a first support 4, a second support 5, an arc roller 6 and a worm and gear mechanism 7;
the guide roller 2 and the tension roller 3 are both arranged on the frame 1;
the first support 4 and the second support 5 are oppositely arranged on the frame and positioned between the guide roller 2 and the tension roller 3; first support 4 is the same with second support 5 structure, all includes: the lower end of the annular supporting plate is fixed at the upper end of the bracket;
the arc-shaped roller 6 comprises a mandrel 8 and a roller sleeve 9, the mandrel 8 is a shaft body with an arc-shaped section, the vertical distance from the middle top of the arc-shaped shaft body to a connecting line of two end points is preferably 1.2mm, one end of the mandrel 8 is sleeved in the annular supporting plate of the first support 4, and the mandrel can rotate in the annular supporting plate of the first support; the roller sleeve 9 is in a hollow cylindrical shape, and the outer surface of the roller sleeve is coated with silicon rubber with good elasticity and compressibility, so that the problem that the copper foil is deformed due to scratching of the copper foil passing through the surface of the arc-shaped roller or excessive tension is avoided; the roller sleeve 9 is sleeved on the mandrel 8, two ends of the roller sleeve are connected with bearings 15 sleeved on the mandrel, and the roller sleeve can rotate on the mandrel through the bearings;
the worm and gear mechanism is powered by a power device and comprises a worm wheel 10 and a worm 11, the worm wheel is meshed with the worm, the worm wheel is sleeved in the annular supporting plate of the second support, and the worm 11 is connected with the other end of the mandrel 8. The surface of the roller sleeve can be bent along with the mandrel to form an arc-shaped surface in the rotating process of the roller sleeve on the mandrel through the bearing, when a material is cut into from the lower point of the arc-shaped surface of the roller sleeve and passes through the higher point of the arc-shaped surface of the roller sleeve, the contact area can be in a process from short to long, and therefore a force from the middle to the edge direction of the material is generated, and the effect of eliminating wrinkles is achieved. The worm and worm wheel mechanism is started through the power device, the worm is meshed with the worm wheel to drive the mandrel to rotate, the roll surface of the roll sleeve on the mandrel lies horizontally towards the horizontal plane, and the roll surface arch height is relatively reduced.
The distance between the guide roll 2 and the arc roll 6 is a leading-in distance, the distance between the arc roll 6 and the tension roll 3 is a leading-out distance, the leading-out distance is 1.5 times of the roll diameter of the arc roll, and the leading-in distance is 2 times or more of the leading-out distance. The length of the mandrel is 1945mm, and the diameter is phi 120; the length of the roller sleeve is 1500 mm.
Adopt measuring equipment structure location installation to location curved roll on leading-in distance is the biggest basis, leading-in distance: 360mm, derive distance: 180 mm. Firstly, a level meter and a dial indicator are utilized to control the parallelism error of a guide roller system to be within 0.02mm, and the horizontal error of the whole roller system is within 0.04 mm; secondly, normally stripping, producing and rolling the copper foil on the basis of no arc roller; and finally, slightly supporting the roller sleeve by using an arc-shaped roller to support the copper foil, wherein the vertical distance from the middle top of a mandrel of the arc-shaped roller to a connecting line of two end points is 1.2mm, so that the optimal effect of flattening the wrinkles is obtained.
When the device is used, when the copper foil 12 is close to the inlet of the arc-shaped roller 6, the edges on two sides of the copper foil start to move laterally towards the end part of the corresponding arc-shaped roller, and stretch slowly to obtain a tensioning effect, so that the anti-wrinkle effect is achieved. When the copper foil contacts the roller surface of the arc-shaped roller, the edge of the copper foil moves laterally further, each point of the copper foil is vertically conveyed out of the roller surface, so that the wrinkle eliminating effect is achieved, and finally the copper foil is obtained through the tension roller 3, the cutter roller 13 and the winding roller 14.
Because the surface grain structure of the lithium-ion electric copper foil is compact, the roughness Ra is controlled within 0.2, and meanwhile, the lithium-ion electric copper foil has the characteristic of certain toughness, and the copper foils with different characteristics can influence the forming effect of the copper foil at the position through different arc heights. In order to obtain a good forming effect when the copper foil is transmitted to the arc-shaped roll surface through the guide roll and prevent the formation of wrinkles, the vertical distance from the middle top of the mandrel to the connecting line of the two end points is determined through a large number of experiments.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention. It should be noted that other equivalent modifications can be made by those skilled in the art in light of the teachings of the present invention, and all such modifications can be made as are within the scope of the present invention.
