[0042] The feeding assembly 100 can be used to deliver the material to be cut to the slitting assembly 200, and the material to be cut is slit by the slitting assembly 200.

[0043] It should be noted that the material to be cut can include anisotropic conductive film (ACF), paper, non-woven fabric, mica tape, film, composite unidirectional tape, etc., which is not limited here.

[0044] The slitting assembly 200 can include a plurality of uniformly distributed cutting blades, which can be used to cut the material to be cut delivered through the slitting assembly 200 into a plurality of narrow strips with the same width, and the cutting direction of the cutting blades is the same as the delivery direction of the material to be cut. Wherein the cutting blade can be a round knife, and can rotate around its own axis. The slitting assembly 200 can cut the material to be cut into narrow strips with a width less than or equal to 1 millimeter. Exemplarily, the width of the narrow strip can be 1 millimeter, 0.8 millimeter or 0.6 millimeter.

[0045] The conveying assembly 300 can include a separation component 310 and a positioning component 320. After the material to be cut is cut into a plurality of narrow strips by the slitting assembly 200, the separation component 310 can be used to separate the plurality of narrow strips, increase the spacing between adjacent narrow strips, and deliver the separated narrow strips to the positioning component 320. The positioning component 320 is located on the side close to the winding assembly 400, and the positioning component 320 can include a plurality of uniformly distributed positioning grooves, which can be used for the plurality of narrow strips to pass through one by one, and the plurality of narrow strips are delivered to the winding assembly 400 at intervals to avoid mutual influence between adjacent narrow strips.

[0046] The winding assembly 400 can include a winding shaft 410 and a plurality of winding grooves 420 sleeved on the winding shaft 410, and the plurality of winding grooves 420 correspond one by one to the positions of the plurality of positioning grooves, and the plurality of winding grooves 420 can be used to wind the plurality of narrow strips, respectively.

[0047] In the embodiment, the plurality of winding grooves 420 are uniformly distributed, each of the winding grooves 420 can wind one slit narrow strip, the winding groove 420 can be composed of two discs sleeved on the winding shaft 410, the width of the winding groove 420 can be the distance between the two discs, and the width of each winding groove 420 is equal.

[0048] In the above structure, the slit narrow strips are separated by the separating component 310, which can increase the spacing between adjacent narrow strips and avoid mutual influence between adjacent narrow strips. In addition, the narrow strips are transported to the winding assembly 400 by the positioning component 320, which can improve the winding effect.

[0049] In a possible implementation, referring again to Figure 1 , the separating component 310 can include a first separating unit 311 and a second separating unit 312.

[0051] In the embodiment, the first separating unit 311 can include at least two separating rollers, and the plurality of slit narrow strips can pass through the at least two separating rollers in sequence to obtain at least two narrow strip groups, and the plurality of narrow strips in each narrow strip group are parallel.

[0052] In some examples, when the first separating unit 311 includes only two separating rollers, the first separating unit 311 can be used to separate the plurality of narrow strips to obtain two narrow strip groups. Specifically, when the plurality of slit narrow strips pass through the first separating roller, a narrow strip group composed of a plurality of narrow strips with odd arrangement numbers can be obtained, and when the plurality of slit narrow strips pass through the second separating roller, a narrow strip group composed of a plurality of narrow strips with even arrangement numbers can be obtained. For example, if the number of slit narrow strips is five, when the plurality of slit narrow strips pass through the first separating roller, a narrow strip group composed of the first narrow strip, the third narrow strip and the fifth narrow strip arranged from left to right (or from right to left) can be obtained, and when the plurality of slit narrow strips pass through the second separating roller, a narrow strip group composed of the second narrow strip and the fourth narrow strip arranged from left to right (or from right to left) can be obtained.

[0053] In addition, the first separating unit 311 can further include a waste conveying roller 500, which can be used to convey the waste after cutting to a waste processing assembly for waste processing.

[0054] The second separating unit 312 can be located in the conveying direction of the narrow strip group, and can be used to separate the plurality of narrow strips in the narrow strip group.

The separating piece 312b can include a plurality of spaced-apart cylinders, and the gap between two adjacent cylinders is a separating opening. The plurality of narrow strips can be transmitted to the positioning assembly through different separating openings, respectively. In addition, the bottom plate 312a is provided with an adjusting hole, which can be a curved and extended strip hole. The two ends of the separating piece 312b can move in the adjusting hole. In this way, the orientation of the separating piece 312b can be adjusted, and the spacing between adjacent narrow strips can be adjusted.

[0056] In a possible implementation, referring to Figure 3 , the winding assembly 400 can further include a first driving component 430 and a second driving component 440. The first driving component 430 and the second driving component 440 can be connected with the winding shaft 410, respectively. The first driving component 430 can be used to drive the winding groove 420 to move along the extension direction of the winding shaft 410. The second driving component 440 can be used to drive the winding shaft 410 to rotate and control the rotating speed of the winding shaft 410, so as to realize the winding of the narrow strip.

[0057] In the embodiment, the winding assembly 400 can further include a sliding block and a plurality of friction rings, which are sleeved on the winding shaft 410.

[0058] The winding assembly 400 can further comprise a first connecting component, one end of the first connecting component being connected with the first driving component 430, the other end of the first connecting component being connected with the winding shaft 410, and the end of the first connecting component connected with the winding shaft 410 can be in contact with the sliding block. The first driving component 430 and the second driving component 440 can be located at the same end of the winding shaft 410, the first driving component 430 can drive the end of the first connecting component connected with the first driving component 430 to move in a direction away from the winding groove 420, so that the end of the first connecting component connected with the winding shaft 410 applies a pushing force to the sliding block, thus the sliding block can push the friction ring to move in a direction close to the winding groove 420, thereby adjusting the distance between the winding grooves 420. When the distance between the adjacent winding grooves 420 decreases, the friction between the winding grooves 420 increases, and the tension of winding increases.

[0059] In the embodiment, the first driving component 430 can be a pneumatic cylinder, and the second driving component 440 can be a driving motor.

[0060] In a possible implementation, referring to Figure 4 The winding assembly 400 can further comprise a fixing component 450 connected with the winding shaft 410, and the fixing component 450 can be used to fix the winding assembly 400.

[0061] In the embodiment, the winding assembly 400 can further comprise a plunger block and a sliding block arranged at opposite ends of the winding shaft 410 respectively, the plunger block can also be in contact with a friction ring, and the fixing component 450 can be in contact with the plunger block and drive the plunger block to abut against the winding shaft 410, thereby fixing the winding assembly 400 and avoiding movement or falling of the winding assembly 400, and the reliability of the winding assembly 400 can be improved.

[0062] In the embodiment, the fixing component 450 can comprise a pneumatic cylinder, and a telescopic rod of the pneumatic cylinder can be used to drive the plunger block to abut against the winding assembly 400. When it is necessary to fix the winding assembly 400, the telescopic rod of the pneumatic cylinder can be extended in a direction close to the plunger block and apply a pressure to the plunger block, so that the plunger block abuts against the winding shaft 410 of the winding assembly 400, thereby fixing the winding assembly 400.

[0063] In a possible implementation, referring to Figure 5The slitting assembly 200 can include a first cutting component 210 and a second cutting component 220. The first cutting component 210 and the second cutting component 220 can be cylindrical, and the extending directions of the first cutting component 210 and the second cutting component 220 are perpendicular to the conveying direction of the material to be cut. The first cutting component 210 can include a first knife shaft and a plurality of first circular knives sleeved on the first knife shaft, and the plurality of first circular knives are parallel to each other. The second cutting component 220 can include a second knife shaft and a plurality of second circular knives sleeved on the second knife shaft, and the plurality of second circular knives are parallel to each other. The plurality of first circular knives correspond to the plurality of second circular knives in position. The plurality of first circular knives and the plurality of second circular knives cooperate with each other to achieve the slitting of the material to be cut.

[0064] In a possible implementation, the distance between adjacent first circular knives is less than or equal to 1 mm, and the distance between adjacent second circular knives is less than or equal to 1 mm.

[0065] In this embodiment, the plurality of first circular knives and the plurality of second circular knives can cooperate with each other to cut the material to be cut into narrow strips with a width of less than or equal to 1 mm. For example, the width of the narrow strip can be 1 mm, 0.8 mm, or 0.6 mm.

[0066] In a possible implementation, referring again to Figure 1 The feeding assembly 100 can include a second connecting component 110, which can be used to connect the plurality of materials to be cut conveyed through the second connecting component 110, so as to increase the length of the material to be cut.

[0067] In this embodiment, when the plurality of materials to be cut pass through the connecting assembly in sequence, the connecting assembly can be used to connect the front and rear materials to be cut passing through the connecting assembly in sequence.

[0068] In a possible implementation, referring again to Figure 1 The feeding assembly 100 can further include a traction roller 120, which can be located between the second connecting component 110 and the slitting assembly 200, and the traction roller 120 can be used to pull the material to be cut to the slitting assembly 200.

[0069] In a possible implementation, referring to Figure 6The transmission belt 600 is arranged between the traction roller 120 and the slitting assembly 200, and can be used to make the rotating speed of the traction roller 120 equal to the conveying speed of the material to be cut, so that the material to be cut is not stretched.

[0070] In addition, the transmission assembly 300 also comprises a plurality of traction rollers, and the transmission assembly 300 also comprises a plurality of transmission belts 600 arranged between the traction rollers. The traction rollers of the feeding assembly 100 and the transmission assembly 300 can all be driving rollers. By arranging the transmission belts 600 between the traction rollers, the rotating speed of the traction rollers can be ensured to be equal to the conveying speed of the narrow strip, so that the narrow strip is not stretched, and the width of the narrow strip during the conveying process is not changed.

[0071] In a possible implementation, referring again to Figure 1 The feeding assembly 100 can also comprise an adjusting component 130 arranged between the traction roller 120 and the slitting assembly 200. The adjusting component 130 can be used to adjust the plane where the material to be cut is tangent to the plurality of cutting blades, so as to facilitate the slitting assembly 200 to cut the material to be cut into a plurality of narrow strips.

[0072] Based on the above design, the working principle of the narrow strip slitting and winding device provided in the embodiment is as follows:

[0073] When the material to be cut is conveyed to the slitting assembly 200, the plurality of materials to be cut can be connected by the second connecting component 110 of the feeding assembly 100, and then be pulled to the adjusting component 130 by the traction roller 120 of the feeding assembly 100. The adjusting component 130 can be used to adjust the plane where the material to be cut is tangent to the plurality of cutting blades of the slitting assembly 200, and then the material to be cut is cut by the slitting assembly 200 to obtain a plurality of narrow strips. The plurality of narrow strips can be obtained as at least two narrow strip groups by the first separating unit 311, and the plurality of narrow strips in the at least two narrow strip groups can be further adjusted in the spacing between the adjacent narrow strips by the second separating unit 312. After the spacing between the plurality of narrow strips in the narrow strip group is adjusted, the plurality of narrow strips can be transmitted to the winding assembly 400 by the plurality of positioning grooves of the positioning component 320, and the plurality of narrow strips are wound.

[0074] In summary, the narrow strip slitting and winding device provided in the embodiment can separate the plurality of narrow strips that have been cut by the separating component, so as to increase the spacing between the adjacent narrow strips and avoid the mutual influence between the adjacent narrow strips. In addition, the narrow strips can be transmitted to the winding assembly by the positioning component, so as to improve the winding effect.
