[0031] It should be noted that the different features in the embodiments of the application can be combined with each other without conflict.

[0032] The specific embodiments of the application will be described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figure 1 , Figure 1 An example of a possible structure of the narrow band winding device provided in the embodiment is shown in the figure. In the embodiment, the narrow band winding device can include a winding assembly 100, a first driving assembly 200 and a second driving assembly 300.

[0034] The winding assembly 100 can include a winding shaft 110 and a plurality of winding grooves 120 sleeved on the winding shaft 110, and the plurality of winding grooves 120 can be arranged in the conveying direction of the slit narrow bands.

[0035] In the embodiment, the winding assembly 100 can include a plurality of uniformly distributed winding grooves 120, each of which can wind a slit narrow band, and the winding groove 120 can be composed of two discs sleeved on the winding shaft 110, the width of the winding groove 120 can be the distance between the two discs, and the width of each winding groove 120 is equal.

[0036] In addition, the width of the slit narrow band can be less than 1mm. The shape of the winding shaft 110 can be cylindrical, and the diameter of the winding shaft 110 can be 15mm.

[0037] It should be noted that the material of the narrow band can include anisotropic conductive film (ACF), paper, non-woven fabric, mica tape, film, composite single tape, etc., which is not limited here, as long as the narrow band winding device can wind it.

[0038] The first driving assembly 200 is connected with the winding assembly 100, and the first driving assembly 200 can be used to drive the winding groove 120 to move along the extension direction of the winding shaft 110.

[0039] In the embodiment, the first driving assembly 200 is connected with one end of the winding shaft 110, and the first driving assembly 200 is used to drive the winding grooves 120 to move along the extension direction of the winding shaft 110, so as to adjust the interval between the winding grooves 120. When the interval between the adjacent winding grooves 120 is reduced, the friction between the winding grooves 120 is increased, and the winding tension is increased.

[0040] The second driving assembly 300 is connected with the winding assembly 100, and the second driving assembly 300 is used to drive the winding shaft 110 to rotate, so as to realize the winding of the narrow band.

[0041] In the embodiment, the second driving assembly 300 and the first driving assembly 200 are located at the same end of the winding shaft 110, and the second driving assembly 300 is used to drive the winding shaft 110 to rotate and control the rotating speed of the winding shaft 110.

[0042] In the above structure, the first driving assembly 200 is used to adjust the interval between the winding grooves 120, so as to control the winding tension, and the second driving assembly 300 is used to drive the winding shaft 110 to rotate, so as to make the winding grooves 120 wind the slit narrow bands respectively. Therefore, the winding efficiency and the winding effect can be improved.

[0043] In a possible implementation, referring to Figure 2 , the winding shaft 110 includes oppositely arranged first and second ends, and the second driving assembly 300 is connected with the first end of the winding shaft 110.

[0044] The narrow band winding device further includes a fixing assembly 400, and the fixing assembly 400 is connected with the second end of the winding shaft 110, and the fixing assembly 400 is used to fix the winding assembly 100.

[0045] In the embodiment, the second driving assembly 300 and the fixing assembly 400 are respectively connected with the first and second ends of the winding shaft 110, so as to fix the winding assembly 100, avoid the movement or falling of the winding assembly 100, and improve the reliability of the narrow band winding device.

[0046] In a possible implementation, referring again to Figure 2The second end of the winding shaft 110 is provided with a needle pressing block 500, the fixing assembly 400 can contact the needle pressing block 500 and drive the needle pressing block 500 to abut against the winding assembly 100, so as to realize the fixing of the winding assembly 100.

[0047] Specifically, the shape of the needle pressing block 500 can be cylindrical.

[0048] In a possible implementation, the fixing assembly 400 can include a pneumatic cylinder, and the telescopic rod of the pneumatic cylinder can be used to drive the needle pressing block 500 to abut against the winding assembly 100.

[0049] In the embodiment, when the winding assembly 100 needs to be fixed, the telescopic rod of the pneumatic cylinder can be extended in a direction close to the needle pressing block 500 and apply pressure to the needle pressing block 500, so that the needle pressing block 500 abuts against the winding shaft 110 of the winding assembly 100, thereby realizing the fixing of the winding assembly 100.

[0050] In other embodiments of the embodiment, the fixing assembly 400 is not limited to the pneumatic cylinder, and can be other fixing assemblies 400, which are not limited herein.

[0051] In a possible implementation, referring again to Figure 2 The first end of the winding shaft 110 is provided with a sliding block 600, and the first driving assembly 200 can drive the sliding block 600 to move along the extension direction of the winding shaft 110, so as to adjust the spacing between the winding grooves 120.

[0052] In the embodiment, the sliding block 600 is sleeved on the winding shaft 110, and the shape of the sliding block 600 can be cylindrical. The first driving assembly 200 can drive the sliding block 600 to move towards the winding grooves 120, so as to drive the winding grooves 120 to move, reduce the spacing between the winding grooves 120, and increase the winding tension.

[0053] In a possible implementation, referring again to Figure 2 The narrow-band winding device can further include a connecting assembly 700, one end of the connecting assembly 700 is connected with the first driving assembly 200, and the other end of the connecting assembly 700 is connected with the winding shaft 110.

[0054] In the embodiment, the end of the connecting assembly 700 connected with the winding shaft 110 can be in contact with the slider 600. The first driving assembly 200 can drive the end of the connecting assembly 700 connected with the first driving assembly 200 to move away from the winding groove 120, so that the end of the connecting assembly 700 connected with the winding shaft 110 applies a pushing force to the slider 600, and thus the slider 600 can move towards the winding groove 120, thereby adjusting the distance between the winding grooves 120.

[0055] In a possible implementation, referring to Figure 3 The width W1 of the winding groove 120 can be less than or equal to 1 mm.

[0056] In the embodiment, the width W1 of the winding groove 120 can be equal to the width of the slit tape. For example, when the width of the slit tape is 1 mm, the width W1 of the winding groove 120 is also 1 mm. When the width of the slit tape is 0.8 mm, the width W1 of the winding groove 120 is also 0.8 mm.

[0057] In addition, since the width W1 of the winding groove 120 is not adjustable, that is, the distance between the two discs constituting the winding groove 120 is constant, in some examples, when it is necessary to adjust the width of the winding groove 120 from 1 mm to 0.8 mm, the original winding groove 120 with a width of 1 mm on the winding shaft 110 can be removed and replaced with a winding groove 120 with a width of 0.8 mm.

[0058] In a possible implementation, referring again to Figure 3 The winding assembly 100 can further include a plurality of friction rings sleeved on the winding shaft 110, and the plurality of friction rings are respectively located between adjacent winding grooves 120.

[0059] In the embodiment, one friction ring is arranged on each side of each winding groove 120, the slider 600 arranged on the first end of the winding shaft 110 can be in contact with one friction ring, and the top pin pressing block 500 arranged on the second end of the winding shaft 110 can also be in contact with one friction ring.

[0060] In a possible implementation, the first driving assembly 200 can include a pneumatic cylinder, and the second driving assembly 300 can include a driving motor.

[0061] In the embodiment, the telescopic rod of the first driving assembly 200 is retracted, which drives the end of the connecting assembly 700 connected with the first driving assembly 200 to move away from the winding groove 120, so that the end of the connecting assembly 700 connected with the winding shaft 110 applies a pushing force to the sliding block 600, and thus the sliding block 600 can push the friction ring to move towards the winding groove 120, thereby adjusting the distance between the winding grooves 120.

[0062] Specifically, when the distance between the winding grooves 120 is adjusted, the pressure of the first driving assembly 200 is small, and thus the friction between the winding grooves 120 is small, and the tension of winding is also small. In this way, the stretching of the narrow band to reduce the width of the narrow band can be avoided, and the bending of the winding shaft 110 during winding can also be prevented.

[0063] The embodiment also provides a slitting and rewinding machine, which can include the narrow band winding device provided by the embodiment.

[0064] In the embodiment, please refer to Figure 4 The narrow band winding device is installed on the rack of the slitting and rewinding machine, and can be combined with other devices to form a slitting and rewinding machine. Specifically, the slitting and rewinding machine can include a third driving assembly 800 and a moving wall 900, and the fixing assembly 400 is fixedly arranged on the moving wall 900. When the winding assembly 100 completes the winding of the narrow band, the telescopic rod of the fixing assembly 400 is retracted, and the third driving assembly 800 can drive the moving wall 900 to move, so that the moving wall 900 is located on one side of the rack of the slitting and rewinding machine, thereby facilitating the removal of the wound narrow band.

[0065] The third driving assembly 800 can be a pneumatic cylinder, and of course in some other embodiments, the third driving assembly 800 is not limited to a pneumatic cylinder, but can also be other driving assemblies, which are not limited here.

[0066] In summary, the embodiment provides a narrow band winding device and a slitting and rewinding machine, the first driving assembly can adjust the distance between the winding grooves to control the tension of winding, and the second driving assembly can drive the winding shaft to rotate to wind the plurality of narrow bands that have been slit by the plurality of winding grooves, respectively. In this way, the winding efficiency and the winding effect can be improved.
