The embodiment of the application provides a slitting device. Referring to fig. 1 to 4, the slitting device 100 includes a bracket 10, a cutting wire 20, a cutting mechanism 30, an adjusting mechanism 40, and at least one tensioning mechanism. The cutting line 20 is arranged on the bracket 10; the cutting mechanism 30 comprises two wire wheels 31 which are arranged on the bracket 10 at intervals, and the cutting wire 20 bypasses the two wire wheels 31 and forms a cutting section 21 between the two wire wheels 31; the adjusting mechanism 40 is in driving connection with at least one wire wheel 31 to drive the at least one wire wheel 31 to move on the support 10. The tensioning mechanism 70 comprises a tensioning drive 71 and a tensioning wheel 72 connected to the tensioning drive 71, the cutting line 20 being wound around the tensioning wheel 72, the tensioning drive 71 being adapted to drive the tensioning wheel 72 towards or away from the support 10.

Specifically, the cutting line 20 extends on the holder 10, and the cutting line 20 is wound around a portion between the two wire wheels 31 to form a cutting section 21, and the cutting section 21 has a cutting force. In some embodiments, the cutting wire 20 will move on the support 10 during cutting, the cutting section 21 between the two wire wheels 31 corresponding to a wire saw; in other embodiments, the cutting segment 21 itself has a stronger cutting force, equivalent to a blade. The cutting line 20 may be subjected to a slitting operation only by means of one or more cutting sections 21.

The bracket 10 is used to provide a mounting base for the cutting wire 20, the cutting mechanism 30 and the adjustment mechanism 40; the dicing line 20 extends on the support 10 and is used for cutting the substrate 300, so that the substrate 300 is cut into strip-shaped products, and taking the substrate 300 as a pole piece substrate as an example, the dicing line 20 can cut the pole piece substrate into pole pieces.

The two wire wheels 31 in the cutting mechanism 30 are used for winding the cutting wire 20, i.e. the cutting wire 20 is wound around the two wire wheels 31 in turn and forms a cutting section 21 between the two wire wheels 31, the cutting section 21 being used for performing a cutting action. The slitting device 100 can include one or more cutting mechanisms 30, where the cutting mechanism 30 is capable of slitting the substrate 300 into two parts when the cutting mechanism 30 is one; when the number of the cutting mechanisms 30 is plural, the plural cutting sections 21 may be used to cut the substrate 300, and in some embodiments, the plural cutting sections 21 may be capable of simultaneously cutting the substrate 300 along the width direction of the substrate 300, and in other embodiments, the plural cutting sections 21 may simultaneously cut plural substrates 300 arranged in parallel.

The adjusting mechanism 40 is in driving connection with at least one wire wheel 31 to drive the at least one wire wheel 31 to move on the support 10, so that the cutting section 21 on the cutting wire 20 moves on the support 10, and the adjustment of the cutting position is realized. The number of the adjusting mechanisms 40 can be one or more, when the adjusting mechanisms 40 are one, the adjusting mechanisms 40 can be connected with one wire wheel 31, or can be connected with a pair of wire wheels 31 at the same time, or can be connected with the wire wheels 31 in a plurality of adjusting mechanisms 40 at the same time; when the plurality of adjusting mechanisms 40 are provided, the plurality of adjusting mechanisms 40 may be provided in one-to-one correspondence with the plurality of cutting mechanisms 30, or each adjusting mechanism 40 may be connected to the plurality of cutting mechanisms 30 at the same time.

The tensioning mechanism 70 is used to provide tension to the cutting line 20. The tensioning mechanism 70 may be provided at either end of the support 10 or between the cutting mechanisms 30.

The working principle of the slitting device 100 is as follows: the substrate 300 to be slit is conveyed to the cutting mechanism 30, and the cutting section 21 between the two wire wheels 31 cuts the substrate 300 to slit the substrate 300; when the cutting position needs to be adjusted, the adjusting mechanism 40 drives the wire wheel 31 connected with the adjusting mechanism to move on the bracket 10, along with the movement of the wire wheel 31, the position of the cutting section 21 on the bracket 10 is adjusted, and then when the base material 300 is cut, the cutting section 21 cuts the base material 300 at the adjusted position, so as to realize cutting at different positions of the base material 300, and realize adjustment of the size of the cut product.

The slitting device 100 includes a bracket 10, a cutting line 20, a cutting mechanism 30 and an adjusting mechanism 40, wherein the cutting mechanism 30 includes two wire wheels 31 arranged on the bracket 10 at intervals, and the cutting line 20 bypasses the two wire wheels 31 and forms a cutting section 21 between the two wire wheels 31; the adjusting mechanism 40 is connected to at least one wire wheel 31 and is used for driving the corresponding wire wheel 31 to move on the bracket 10, wherein the wire wheel 31 corresponding to the adjusting mechanism 40 refers to the wire wheel 31 in driving connection with the adjusting mechanism 40. In this way, the slitting device 100 cuts the substrate 300 by using the cutting section 21, and the adjusting mechanism 40 can drive the wire wheel 31 to move so as to adjust the position of the cutting section 21 on the support 10. The above-mentioned cutting device 100 can cut the substrate 300 and automatically regulated cutting position, and then adjust and cut the size to adapt to different needs of cutting, the above-mentioned cutting device 100 has solved the problem that traditional cutting device 100 is inconvenient for adjusting cutting position, labour saving and time saving has promoted production efficiency. Compared with the traditional slitting device 100, the slitting device 100 provided by the application does not need to detach and reinstall the blade, and the adjustment process is simple and convenient.

Since the slitting device 100 is convenient for adjusting the cutting position, for example, when the slitting device 100 is applied to slit pole pieces, the slitting device 100 can adjust the size of the slit pole pieces by adjusting the cutting position.

In some embodiments, as shown in fig. 1, 3, 5, two wire wheels 31 in the cutting mechanism 30 are spaced apart along a first direction; the adjusting mechanism 40 is used for driving at least one wire wheel 31 to move along a second direction, and the second direction intersects with the first direction and the conveying direction of the substrate 300.

For ease of understanding, the state before adjusting the cutting position is referred to as an initial state, and the two wire wheels 31 are disposed at intervals in the first direction in the initial state, and the cutting segment 21 also extends in the first direction. After the adjustment mechanism 40 drives the wire wheel 31 to move along the second direction, the position of the cutting segment 21 in the second direction is changed.

By adopting the above technical scheme, the adjusting mechanism 40 can drive to move along the direction different from the cutting section 21 to adjust the cutting position, and the adjusting mode is simple and convenient.

In other embodiments, the adjusting mechanism 40 may also drive the at least one wire wheel 31 to move along the first direction.

In some embodiments, as shown in fig. 1, 3, and 5, the second direction is perpendicular to the first direction. The first direction is the X direction, and the second direction is the Y direction.

Alternatively, the first direction X is a vertical direction and the second direction Y is a horizontal direction, but the present invention is not limited thereto, and the transfer direction of the substrate 300 may be perpendicular to the first direction X and the second direction Y. In this embodiment, the conveying direction of the substrate 300 is the Z direction.

In some cases, the position of only one reel 31 needs to be adjusted, the adjusting mechanism 40 is only connected to one reel 31, and after the adjusting mechanism 40 drives the corresponding reel 31 to move along the second direction Y, the cutting section 21 is inclined relative to the first direction X, so that the slitting device 100 can adjust the angle of the cutting section 21 to change the shape of the slit product. For example, the substrate 300 may be a sheet or plate having a thickness, and the obliquely disposed cutting segments 21 may provide the cut product with oblique sides.

In other cases, the positions of the two reels 31 need to be adjusted synchronously, and the adjusting mechanism 40 connects the two reels 31, so that after the adjusting mechanism 40 moves the corresponding reels 31 along the second direction Y, the cutting line 20 still extends along the first direction X, but the position of the cutting line 20 on the support 10 is changed, and thus the slitting device 100 will adjust the width of the slit product.

By adopting the above-described technical solution, the adjusting mechanism 40 is used to drive the wire wheel 31 to move in a direction different from the cutting section 21, so as to adjust the position of the cutting section 21.

For example, the guide rod 12 extends along the second direction Y, and the adjusting mechanism 40 drives the wire wheel 31 connected with the guide rod to move along the guide rod 12, so that the position of the wire wheel 31 along the second direction Y can be adjusted, and the position of the cutting segment 21 can be adjusted.

In some embodiments, the guide rod 12 may be rod-shaped, and the wire wheel 31 is slidably sleeved on the rod-shaped guide rod 12.

In the embodiment, the pulley 31 may be slidably connected to the guide rod 12, and the form of the sliding connection between the guide rod 12 and the pulley 31 is not limited.

The adjustment unit 41 comprises two adjustment units 41, whereby each adjustment unit 41 can independently drive one reel 31. The adjusting unit 41 includes a driving assembly 411 and a slider 412, and the wire wheel 31 is slidably coupled with the guide rod 12 through the slider 412 to facilitate mounting the wire wheel 31 on the guide rod 12. The driving component 411 is in driving connection with the sliding component 412, and the driving component 411 drives the sliding component 412 to slide along the guide rod 12 so as to drive the corresponding wire wheel 31 to move along the guide rod 12. The structure of the driving assembly 411 may be various manners, for example, the driving assembly 411 may be a screw driving, a belt driving, or a gear driving, and the specific structure of the driving assembly 411 is not limited herein, as long as the driving assembly 411 can drive the sliding member 412 to slide along the guide rod 12.

By adopting the technical scheme, the two adjusting units 41 respectively drive the corresponding wire wheels 31 to move, and the slitting device 100 can conveniently adjust the width of the slit single product; the two adjusting units 41 are independently arranged to independently drive the two wire wheels 31 to move, so that the risk of obstructing the conveying of the substrate 300 due to the arrangement of the adjusting mechanism 40 can be reduced.

In some embodiments, two of the adjustment units 41 are used to drive the two slides 412 to move synchronously, causing the two wire wheels 31 to move synchronously to adjust the position of the cutting segment 21.

When the number of the cutting mechanisms 30 is plural, a plurality of adjusting mechanisms 40 may be provided correspondingly to drive the wire wheels 31 of the corresponding cutting mechanisms 30 to move, respectively, and adjust only part of the cutting mechanisms 30; the present application does not limit whether the plurality of adjustment units 41 move synchronously.

The end of the sliding member 412 away from the reel 31 is provided with a sliding pin 413, and the sliding pin 413 is inserted into the slideway 4123 and can slide in the slideway 4123. Alternatively, the two ends of the sliding pin 413 respectively abut against two opposite side walls of the slideway 4123, so as to push the sliding pin 413 to move through the slideway 4123.

By adopting the above technical scheme, the adjusting driving member 4111 can drive the sliding member 412 and the wire wheel 31 to move through the guiding member 4112 and the sliding pin 413, so as to adjust the positions of the wire wheel 31 and the cutting segment 21 on the bracket 10.

The number of the adjusting mechanisms 40 is one or more, and the adjusting mechanisms 40 can drive the corresponding wire wheels 31 to move. Wherein the slitting device 100 can adjust the position of one or more of the cutting mechanisms 30.

The pole piece part can be used in a battery, and comprises a current collector and an active material part coated on the current collector, wherein the part of the current collector, which is not coated with the active material part, is an empty foil area. The slitting device 100 can adjust the position of one of the cutting mechanisms 30 to adjust the spacing between the corresponding cutting segment 21 and the adjacent cutting segment 21, thereby adjusting the slitting width. For example, if the slitting device 100 only adjusts the position of the centrally located slitting mechanism 30, the width of the pole piece portions on either side of the slitting section 21b will be adjusted.

Of course, the slitting device 100 can also adjust the positions of the plurality of cutting mechanisms 30 at the same time, and if the adjacent cutting mechanisms 30 move synchronously, the slitting width is not adjusted, and only the slitting position is adjusted; if adjacent cutting mechanisms 30 do not move synchronously, the slit width is adjusted.
