[0036] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0037] The specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings.

[0038] Please refer to Figure 1 , Figure 1 The schematic structural diagram of the narrow tape slitting and winding device provided by the present embodiment is shown as an example.

[0039] The feeding assembly 100 can be used to convey the material to be cut to the slitting assembly 200, and the slitting assembly 200 slitting the material to be cut.

[0040] It should be noted that the material to be cut may include anisotropic conductive film (ACF), paper, non-woven fabric, mica tape, film, composite material unidirectional tape, etc., and is not specifically limited here.

[0041] The slitting assembly 200 may include a plurality of evenly distributed cutting blades, which may be used to cut the material to be cut conveyed through the slitting assembly 200 into a plurality of narrow strips of the same width, and the cutting direction of the plurality of cutting blades is the same as the conveying direction of the material to be cut. The cutting blade may be a circular blade, and may rotate with its own axis as the rotating axis. The slitting assembly 200 may cut the material to be cut into narrow strips with a width less than or equal to 1 mm. Exemplarily, the width of the narrow strip may be 1 mm, 0.8 mm, or 0.6 mm.

[0042] The conveying assembly 300 may include a separation component 310 and a positioning component 320. After the material to be cut is cut into a plurality of the narrow strips by the slitting assembly 200, the separation component 310 may be used to separate the plurality of the narrow strips, increase the spacing between adjacent narrow strips, and convey the separated narrow strips to the positioning component 320. The positioning component 320 is located on a side close to the winding assembly 400. The positioning component 320 may include a plurality of evenly distributed positioning grooves. The plurality of positioning grooves may be used to allow the plurality of narrow strips to pass through one by one, and convey the plurality of narrow strips to the winding assembly 400 at intervals to avoid mutual influence between adjacent narrow strips.

[0043] The winding assembly 400 may include a winding shaft 410 and a plurality of winding slots 420 sleeved on the winding shaft 410, wherein the plurality of winding slots 420 correspond to the positions of the plurality of positioning slots one by one, and the plurality of winding slots 420 may be used to wind up the plurality of narrow bands respectively.

Specifically, when the plurality of narrow bands that have been cut pass through the first separation roller, the narrow band group consisting of the plurality of narrow bands whose arrangement sequence is an odd number can be obtained, and when the plurality of narrow bands that have been cut pass through the second separation roller, the narrow band group consisting of the plurality of narrow bands whose arrangement sequence is an even number can be obtained. For example, if the number of the plurality of narrow bands that have been cut is five, when the plurality of narrow bands that have been cut pass through the first separation roller, the narrow band group consisting of the first narrow band, the third narrow band and the fifth narrow band arranged from left to right (or from right to left) can be obtained; when the plurality of narrow bands that have been cut pass through the second separation roller, the narrow band group consisting of the second narrow band and the fourth narrow band arranged from left to right (or from right to left) can be obtained.

When the spacing between adjacent winding grooves 420 decreases, the friction between the winding grooves 420 increases, and the winding tension increases.

[0056] The first driving component 430 may be a cylinder, and the second driving component 440 may be a driving motor.

[0057] In one possible implementation, see Figure 4 The winding assembly 400 may further include a fixing component 450 , wherein the fixing component 450 is connected to the winding shaft 410 , and the fixing component 450 may be used to fix the winding assembly 400 .

[0059] The fixing component 450 may include a cylinder, and the telescopic rod of the cylinder may be used to drive the ejector pressing block to abut against the winding assembly 400. When the winding assembly 400 needs to be fixed, the telescopic rod of the cylinder may extend in a direction close to the ejector pressing block and apply pressure to the ejector pressing block, so that the ejector pressing block abuts against the winding shaft 410 of the winding assembly 400, thereby fixing the winding assembly 400.

[0064] In this embodiment, when a plurality of the materials to be cut pass through the connecting component in sequence, the connecting component can be used to connect together the front and rear two materials to be cut that pass through the connecting component in sequence.

[0065] In one possible implementation, please refer again to Figure 1 The feeding assembly 100 may further include a traction roller 120 , and the traction roller 120 may be located between the connecting component 110 and the slitting assembly 200 , and the traction roller 120 may be used to pull the material to be cut to the slitting assembly 200 .

[0066] In one possible implementation, see Figure 6 A conveyor belt 600 is provided between the traction roller 120 and the slitting assembly 200.

[0067] In addition, the conveying assembly 300 also includes a plurality of traction rollers, and a conveyor belt 600 is also provided between the plurality of traction rollers of the conveying assembly 300. The traction rollers of the feeding assembly 100 and the conveying assembly 300 can both be active rollers, and by providing the conveyor belt 600 between the traction rollers, it can be ensured that the rotation speed of the traction rollers is equal to the conveying speed of the narrow belt, so as to avoid stretching the narrow belt and prevent the width of the narrow belt from changing during the conveying process.

[0068] In one possible implementation, please refer again to Figure 1 The feeding assembly 100 may further include an adjusting component 130, and the adjusting component 130 is located between the traction roller 120 and the slitting assembly 200.

[0069] Based on the above design, the working principle of the narrow band slitting and winding device provided in this embodiment is as follows:

[0070] When the material to be cut is transported to the slitting component 200, the plurality of materials to be cut can be connected by the connecting component 110 of the feeding component 100 first, and then pulled to the adjusting component 130 by the traction roller 120 of the feeding component 100. The adjusting component 130 can be used to adjust the plane where the material to be cut is located to be tangent to the plurality of cutting blades of the slitting component 200. Then, the slitting component 200 cuts the material to be cut to obtain a plurality of narrow bands. The plurality of narrow bands can be obtained by the first separation unit 311 to obtain at least two narrow band groups. The plurality of narrow bands in at least two narrow band groups can further adjust the spacing between adjacent narrow bands via the second separation unit 312. After adjusting the spacing between the plurality of narrow bands in the narrow band group, the plurality of narrow bands can be transmitted to the winding component 400 at intervals by the plurality of positioning grooves of the positioning component 320, and the plurality of narrow bands can be wound.

[0071] In summary, this embodiment provides a narrow band slitting and winding device, which can increase the spacing between adjacent narrow bands and avoid mutual influence between adjacent narrow bands by separating the multiple slit narrow bands through the separation component. In addition, the narrow bands can be transported to the winding component at intervals through the positioning component, which can improve the winding effect.
