Fig. 1 and 2 are schematic views of a roll cutting mechanism according to some embodiments of the present disclosure. The roll cutting mechanism 100 includes: the roller assembly comprises a first roller 110 and a second roller 210, wherein the first roller 110 and the second roller 210 are oppositely arranged, the axes are parallel, and the distance between the axes is adjustable. The first roll 110 includes: a first main roll 130, a first die roll 150. The second roll 210 includes: a second main roll 230, which is opposite to the first main roll 130 and has the same size, and a second die roll 250.

The roll cutting mechanism 100 needs the first main roll 130 and the second main roll 230 to cooperate with each other when in operation, and the target cutting object 101 is wound into the gap between the first main roll 130 and the second main roll 230. The first roll 110 and the second roll 210 are disposed opposite to each other and are axially parallel, and then the first main roll 130 and the second main roll 230 are also parallel and are oppositely disposed, as shown in fig. 1 and 2. When the target cut object 101 is wound into the gap between the first roller 110 and the second roller 210, the roller surfaces of the first roller 110 and the second roller 210 are all in full contact with the target contact cut object 101, so that the two directions of the friction force applied to the target cut object 101 are the same, and the target cut object cannot be deviated after entering the gap between the first roller 110 and the second roller 210.

The roll cutting mechanism 100 further comprises a frame 200 vertically arranged on the working surface; the first mounting shafts 140 are disposed at the axial centers of the two end surfaces of the first main roller 130 and detachably connected to the frame 200; and a second mounting shaft 240 provided at the axial centers of both end surfaces of the second main roller 230 and detachably coupled to the frame 200.

The frame 200 includes an upper frame 201 and a lower frame 203, the first main roller 130 is installed in the upper frame 201, and the second main roller 230 is installed in the lower frame 203. In some embodiments, the target cutting object 101 is a battery tab, the tabs of the battery having different size models. The first main roller 130 and the second main roller 230 are detachably mounted on the frame 200 through the first mounting shaft 140 and the second mounting shaft 240 respectively, and only the corresponding main roller and the cutting die roller need to be replaced when battery tabs of different sizes are cut, so that the roll cutting mechanism 100 can be applied to roll cutting of different battery tabs.

As shown in fig. 1 and 2, the roll cutting mechanism 100 further includes: a first driving device 170 mounted on the frame 200, connected to the first mounting shaft 140, and configured to drive the first roller 110 to roll; a second driving device 270 mounted on the frame 200, connected to the second mounting shaft 240, and configured to drive the second roller 210 to roll. In some embodiments of the present application, the first pressing roller 110 is integrally coupled to the first mounting shaft 140, and the second pressing roller 210 is integrally coupled to the first mounting shaft 240.

When the first driving device 170 and the second driving device 270 respectively drive the first roll 110 and the second roll 210, the roll cutting mechanism 100 needs to ensure that the rotation of the first roll 110 and the second roll 210 is synchronous. The first driving means 170 and the second driving means 270 may be servo motors, which can control the speed and position of the rotating shaft accurately, and have no rotation phenomenon when the input signal voltage is zero, and are very suitable for being used as driving means of the roll cutting mechanism 100.

When the first rolling roller 110 and the second rolling roller 210 synchronously roll in different directions during operation, the first main roller 130 and the second main roller 230 synchronously roll in different directions. The first main roller 130 and the second main roller 230 have the same size, and the rolling distance of the roller surfaces contacting with the target cutting object 101 is the same when the rollers roll synchronously, so that the problem that one main roller rubs the surface of the target cutting object 101 to damage the target cutting object 101 when the first main roller 130 and the second main roller 230 rotate at different distances is avoided. When the first roller 110 and the second roller 210 roll in different directions, the target cutting object 101 can be continuously driven forwards, so that continuous roll cutting is realized.

The first die roller 150 has the same diameter as the first main roller 130 and is coaxially arranged on two end faces of the first main roller 130; the second die cylinder 250 has the same diameter as the second main cylinder 230 and is coaxially installed at both end surfaces of the second main cylinder 230. When the first main roller 130 and the second main roller 230 move, the first cutting die roller 150 and the second cutting die 250 are respectively driven to synchronously rotate, the roller surfaces of the first main roller 130 and the first cutting die roller 150 synchronously contact the target cutting object 101, and abnormal deformation of the target cutting object 101 caused by asynchronous rotation or different diameters of the first cutting die roller 150 and the first main roller 130 during rolling is avoided. Similarly, the roll surfaces of the second main roll 230 and the second die roll 250 also synchronously contact the target cut object 101, so that abnormal deformation of the target cut object 101 is not caused.

The first die cylinder 150 includes a first mounting hole 151 along the axial direction, the first mounting hole 151 is adapted to the first mounting shaft 140, and can be disposed through the first mounting shaft 140 to sleeve the first die cylinder 150 on the first mounting shaft 140, so that the first die cylinder 150 is disposed on two side surfaces of the first main cylinder 130.

The first insert die roll 150 further comprises at least one first mounting screw hole 155 which is parallel to the axial direction and penetrates through the first insert die roll 150, and the first main roll 130 comprises at least one first main roll mounting screw hole 133 which corresponds to and is matched with the first mounting screw hole 155 in position. The first insert die roll 150 is fixedly mounted at both side surfaces of the first main roll 130 through the first main roll mounting screw holes 133 and the first mounting screw holes 155.

The second die cylinder 250 includes a second mounting hole 251 along the axial direction, the second mounting hole 251 is adapted to the second mounting shaft 240 and can be disposed through the second mounting shaft 240 to sleeve the second die cylinder 250 on the second mounting shaft 240, so that the second die cylinder 250 is disposed on two sides of the second main cylinder 230.

The second die cylinder 250 further comprises at least one second mounting screw hole 255 which is parallel to the axial direction and penetrates through the second die cylinder 250, and the second main cylinder 230 comprises at least one second main cylinder mounting screw hole 233 which corresponds to and is matched with the second mounting screw hole 255. The second die cylinder 250 is fixedly mounted on both side surfaces of the second main cylinder 230 by fixedly coupling the second main cylinder mounting screw hole 233 and the second mounting screw hole 255 with a coupling screw.

The first mounting hole 151 and the second mounting hole 251 are respectively disposed at the axial centers of the first die cylinder 150 and the second die cylinder 250, the first die cylinder 150 and the second die cylinder 250 are respectively disposed at both sides of the first main cylinder 130 and the second main cylinder 230 through the first mounting hole 151 and the second mounting hole 255, and the first die cylinder 150 is coaxially rotated along with the first main cylinder 130, and the second die cylinder 250 is coaxially rotated along with the second main cylinder 230.

When the first cutting die cylinder 150 rotates coaxially with the first main cylinder 130, it may occur that the friction force of the target cutting object 101 with the first cutting die cylinder 150 is too large, resulting in the first cutting die cylinder 150 rotating out of sync with the first main cylinder 130. And the first mounting screw hole 155 cooperates with the first main roller mounting screw hole 133 to solve the above-mentioned problems. Screws are used to penetrate through the first mounting screw holes 155 and the first main roll mounting screw holes 133 to fixedly connect the first cutting die 150 to both sides of the first main roll 130, so that the first cutting die 150 is ensured to rotate synchronously along with the first main roll 130.

Similarly, the second die cylinder 250 and the second main cylinder 230 may not rotate synchronously, and the second mounting screw hole 255 and the second main cylinder mounting screw hole 233 may overcome the problem.

The first cutting die roller 150 comprises a first blade 153, the first blade 153 is matched with the target cutting object 101, and the first blade 153 is a convex blade uniformly distributed on the roller surface of the first cutting die roller 150; the second cutting die roller 250 comprises a second cutting edge 253 which is matched with the target cutting object 101, the second cutting edge 253 is a concave cutting edge which is uniformly distributed on the roller surface of the second cutting die roller 250, and when the roll cutting mechanism 100 works, the first cutting edge 153 is meshed with the second cutting edge 253.

The first cutting die roller 150 and the second cutting die roller 250 are rolling cutting structural members of the rolling cutting mechanism 100, and the shapes of the first cutting edge 153 and the second cutting edge 253 determine the shape of the target cut object 101 after rolling cutting. The first blade 153 and the second blade 253 are respectively a convex blade and a concave blade which are mutually matched, and when the first die cylinder 150 and the second die cylinder 250 are arranged, the positions of the first blade 153 and the second blade 253 are opposite, and the convex blade is just matched with the concave blade when the first die cylinder is rolled. When the first blade 153 is not opposite to the second blade 253, the first blade 153 is prevented from being in rigid contact with the target cutting object 101, so that the roll cutting effect is poor, and the damage to parts such as the first blade 153 and the second blade 253 can be avoided.

The first die cylinder 150 and the second die cylinder 250 roll in different directions in synchronization with the first main roller 130 and the second main roller 230, and the first blade 153 and the second blade 253 continuously roll the object to be cut 101. In some embodiments, the target cutting object 101 is a battery tab. According to the size specification of the battery tab to be produced, the length of a single battery tab is determined, then the first cutting die roller 150 and the second cutting die roller 250 are determined to be cut for one circle to obtain a plurality of battery tabs, and then the size of the structural component of the roll cutting mechanism 100 to be used or manufactured can be determined.

Referring to fig. 3, which shows the battery tab after roll cutting in some embodiments, the roll cutting mechanism 100 rolls the tab in a state where a plurality of tabs are connected together, and needs to be cut to obtain a single tab, and the distance between adjacent tabs is the length of a complete pole piece. The perimeter of the die cylinder is equal to the sum of the lengths of the N pole pieces, N being a positive integer greater than 1, e.g., 4, 6, etc.

As shown in fig. 1 and 2, the first insert die roller 150 further comprises a first groove 157 arranged on the roller surface of the first insert die roller 150; and an elastic member 159 disposed in the first recess 157, wherein a surface of the elastic member 159 protrudes from a surface of the first blade edge 153. The second die cylinder 250 includes a second concave groove 257 provided on a roll surface of the second die cylinder 250 at a position opposite to the elastic member 159.

In the roll cutting mechanism 100, the first blade 153 moves into the second blade 253 during roll cutting, and in an ideal situation, the first blade 153 does not contact the second blade 253 too much, but the roll cutting mechanism 100 inevitably generates some vibration during operation, which may cause the first blade 153 to contact the second blade 253 too much, and the elastic member 159 is used for responding to the situation.

Fig. 4 is a partially enlarged schematic view of a die-cutting mechanism according to some embodiments of the present disclosure. In the process of roll cutting by the roll cutting mechanism 100, the protruding portion of the elastic member 159 is located in the second concave groove 257, the depth H2 of the second concave groove 257 is smaller than the depth H1 of the second blade 253, and when a shock occurs, the elastic member 159 contacts the groove bottom of the second concave groove 257 before the first blade 153 contacts the second blade 253, so as to play a role in buffering, prevent the first blade 153 from contacting the second blade 253 too much, and further prolong the service life of the die roller.

The roll cutting mechanism 100 further includes: at least one distance adjusting device 160 installed on the stand 200, wherein the distance adjusting device 160 is configured to adjust the distance between the first roll 110 and the second roll 210.

The target cut object 101 is located between the first rolling roller 110 and the second rolling roller 210 during rolling cutting, a gap at the minimum distance between the first rolling roller 110 and the second rolling roller 210 is slightly smaller than the thickness of the target cut object 101, so that the target cut object 101 can be pressed and shaped for the second time during rolling cutting, the target cut object 101 is not easy to deviate, meanwhile, the rolled part of the target cut object 101 during rolling cutting may generate certain deformation, and the first rolling roller 110 and the second rolling roller 210 can roll the deformed part back to the original shape, so that the consistency of the target cut object 101 after rolling cutting is ensured.

Taking the battery tab as an example, the shape, size and thickness of the battery tab to be produced are different, and the roll cutting mechanism 100 can adjust the distance between the first rolling roll 110 and the second rolling roll 210 through the distance adjusting device 160 to adapt to the battery tabs with different thicknesses.

As shown in fig. 5, which is a schematic view of a distance adjusting device in some embodiments of the present application, the distance adjusting device 160 is a ball screw, and includes a screw 161 and a nut 163. The distance adjusting device 160 is installed in a gap between the upper frame 201 and the lower frame 203, wherein the nut 163 is fixed on the lower frame 203, the screw 161 is installed in the nut 163, one end of the screw penetrates through the lower frame 203, and the other end of the screw is fixedly connected to the upper frame 201. The length of the screw 161 between the upper frame 201 and the lower frame 203 is adjusted by controlling the nut 163, so that the upper frame 201 is close to or far away from the lower frame 203, and the purpose of adjusting the distance between the first roller 110 and the second roller 210 is achieved. The actual number of pitch devices 160 installed in the roll cutting mechanism 100 is determined by the weight of the actual roll cutting mechanism and is not limited to the two shown in fig. 1.

As shown in fig. 6, which is a left side view of the roll cutting mechanism in some embodiments of the present application, the roll cutting mechanism 100 further includes a deviation correcting mechanism 180 disposed on the frame 200, and the deviation correcting mechanism 180 is configured to adjust a position of the target cutting object 101 entering the roll cutting mechanism 100.

The deviation rectifying mechanism 180 includes a distance measuring sensor 183 and a deviation rectifying executing mechanism 181. The distance measuring sensor 183 may be disposed on one side of the target cutting object 101, or may be disposed on two sides of the target cutting object 101, and measures a distance from a side of the target cutting object 101 close to the distance measuring sensor 183.

The deviation rectifying executing mechanism 181 may be a ball screw mechanism capable of driving the target cutting object 101 to move to the left and right sides of the advancing direction, and the deviation rectifying executing mechanism 181 adjusts the position of the target cutting object 101 according to the distance measured by the distance measuring sensor 183. For example, the distance detected by the distance sensor 183 on one side is 0.5mm, the distance limit from the side of the marked cutting object 101 close to the distance sensor 183 is set to be 0.8mm, the deviation rectifying actuator 181 drives the target cutting object 101 to move to the other side, and the deviation rectifying actuator 181 stops working only when the distances detected by the distance sensors 183 on both sides are equal to about 0.8 mm.

As shown in fig. 6, the roll cutting mechanism 100 further includes a cooling device 190 disposed on the frame 200 and facing the first and second die

cylinders

150 and 250, wherein the cooling device 190 is configured to reduce the temperature of the first and second die

cylinders

150 and 250 during operation.

When the roll cutting mechanism 100 operates, the first cutting die roller 150 and the second cutting die roller 250 roll-cut the target cutting object 101 continuously, the temperature of the first cutting die roller 150 and the temperature of the second cutting die roller 250 may rise, and when the temperature is too high, abnormal deformation of the target cutting object 101 may be caused, and the service life of the cutting die rollers may also be affected. The cooling device 190 may be a plurality of air knives installed on the machine frame 200, and the air outlets of the air knives are opposite to the first cutting die roller 150 and the second cutting die roller 250, and when the roll cutting mechanism 100 operates, the air knives continuously blow air to the first cutting die roller 150 and the second cutting die roller 250 for cooling. In actual production, the air knife can be replaced by other cooling devices, such as cooling water flowing through an internal design flow channel, according to the heat generation of the first cutting die roller 150 and the second cutting die roller 250.
