[0027] It should be noted that, without conflict, the features in the embodiments of the present application can be combined with each other.
[0028] The inventors of the present application have found that in the existing cutting process of the pole piece strip, the cutting knife cuts perpendicular to the surface of the pole piece strip to achieve the purpose of cutting the pole piece. However, in this way, the pole piece strip may not be cut off during the cutting process, reducing the success rate of automatic roll change. The embodiments of the present application provide a pole piece cutting device, which at least solves this technical problem.
[0029] Please refer to Figures 1 - 3 , the pole piece cutting device provided by the embodiments of the present application includes a mounting base 1, a cam follower plate 2, a driving mechanism 3, a cutter fixing seat 4 and a cutter 5; the cam follower plate 2 and the driving mechanism 3 are both arranged on the mounting base 1. A guide groove 21 is arranged on the cam follower plate 2. The cutter fixing seat 4 is slidably matched with the guide groove 21. The driving mechanism 3 is connected to the cutter fixing seat 4. The driving mechanism 3 is used to drive the cutter fixing seat 4 to slide along the guide groove 21. The cutter 5 is arranged on the cutter fixing seat 4. The cutter 5 is used to cut the pole piece strip along the width direction of the pole piece strip.
[0030] It should be noted that the mounting base 1 includes two relatively arranged substrates. The cam follower plate 2 is connected between the two substrates, and the driving mechanism 3 is connected between the two substrates; during the process of the cutter fixing seat 4 sliding along the guide groove 21, the cutter 5 cuts the pole piece strip along the width direction of the pole piece strip.
[0031] During the process of cutting the pole piece strip, the driving mechanism 3 drives the cutter fixing seat 4 to slide along the guide groove 21, and the cutter 5 moves synchronously with the cutter fixing seat 4. During the movement, the cutter 5 cuts the pole piece strip along the width direction of the pole piece strip. Compared with the way of cutting perpendicular to the surface of the pole piece strip, it is easier to cut off the pole piece strip, and the cut of the pole piece strip is relatively flat, improving the success rate of automatic roll change.
[0032] In this embodiment, the driving mechanism 3 includes a cylinder 31, a first guiding shaft 32, and a linear bearing mounting block 33. The cylinder 31 and the first guiding shaft 32 are both arranged on the mounting base 1. The cylinder 31 is connected to the linear bearing mounting block 33, and the linear bearing mounting block 33 is slidably engaged with the first guiding shaft 32. The cutter fixing seat 4 is arranged on the linear bearing mounting block 33.
[0033] It should be noted that the cylinder 31 is connected between two substrates, and the first guiding shaft 32 is connected between two substrates.
[0034] When the cylinder 31 is started, the cylinder 31 drives the linear bearing mounting block 33 to slide on the first guiding shaft 32, and the cutter fixing seat 4 and the cutter 5 move together with the linear bearing mounting block 33, thereby realizing transverse cutting of the pole piece strip.
[0035] In this embodiment, the pole piece cutting device further includes a roller 6. The roller 6 is arranged on the mounting base 1. The cam follower plate 2, the cylinder 31, the first guiding shaft 32, the linear bearing mounting block 33, and the cutter fixing seat 4 are all located inside the roller 6. A through hole for the cutter 5 to extend out is formed on the roller 6.
[0036] It should be noted that both ends of the roller 6 are respectively connected to two substrates. The cutter 5 can extend out through the through hole on the roller 6. The cam follower plate 2, the cylinder 31, the first guiding shaft 32, the linear bearing mounting block 33, and the cutter fixing seat 4 are all located inside the roller 6. The roller 6 can play a role in protecting the cam follower plate 2, the cylinder 31, the first guiding shaft 32, the linear bearing mounting block 33, and the cutter fixing seat 4.
[0037] In this embodiment, a first linear bearing is arranged inside the linear bearing mounting block 33, and the linear bearing mounting block 33 is slidably engaged with the first guiding shaft 32 through the first linear bearing.
[0038] The first linear bearing is arranged inside the linear bearing mounting block 33, and the first guiding shaft 32 passes through the first linear bearing. When the linear bearing mounting block 33 slides along the first guiding shaft 32, the first linear bearing can make the movement process of the linear bearing mounting block 33 smoother.
[0039] In this embodiment, the guide groove 21 includes a connected horizontal groove section 211 and an inclined groove section 212. A second guiding shaft 331 is slidably arranged on the linear bearing mounting block 33. The cutter fixing seat 4 is connected to the second guiding shaft 331. The cutter fixing seat 4 can slide between the horizontal groove section 211 and the inclined groove section 212. When the cutter fixing seat 4 slides from the inclined groove section 212 to the horizontal groove section 211, the cutter 5 extends out of the through hole.
[0040] It should be noted that the horizontal groove section 211 and the inclined groove section 212 are connected, and one end of the inclined groove section 212 far from the horizontal groove section 211 extends towards the inside of the roller 6; the length direction of the second guide shaft 331 is perpendicular to the length direction of the first guide shaft 32. When the cutter holder 4 slides in the horizontal groove section 211, the cutter 5 extends out of the through hole, and at this time the cutter 5 is in the working state and can cut the pole piece strip; when the cutter holder 4 slides from the horizontal groove section 211 to the inclined groove section 212, the cutter 5 retracts into the inside of the roller 6, and at this time the cutter 5 is in the non-working state. The cutter 5 can avoid damaging personnel or other equipment in the non-working state.
[0041] During the process of cutting the pole piece strip, the cutter holder 4 drives the cutter 5 to move from the first position A to the second position B. At this time, the cutter 5 extends out of the through hole and switches from the non-working state to the working state. Subsequently, the cutter holder 4 drives the cutter 5 to move from the second position B to the third position C to cut the pole piece strip. After the cutting is completed, the cutter holder 4 drives the cutter 5 to move from the third position C to the first position A. At this time, the cutter 5 retracts into the inside of the roller 6 and switches from the working state to the non-working state. Among them, the first position A is located at one end of the inclined groove section 212 far from the horizontal groove section 211, and the second position B and the third position C are respectively located at both ends of the horizontal groove section 211.
[0042] In this embodiment, a cam follower 41 is provided on the cutter holder 4, and the cam follower 41 is selectively slidably engaged with the horizontal groove section 211 and the inclined groove section 212.
[0043] It should be noted that the cam follower 41 is selectively slidably engaged with the horizontal groove section 211 and the inclined groove section 212, so that the cam follower 41 can slide between the horizontal groove section 211 and the inclined groove section 212. When the cam follower 41 slides to the horizontal groove section 211, the cutter 5 is in the working state; when the cam follower 41 slides from the horizontal groove section 211 to the inclined groove section 212, the cutter 5 is in the non-working state.
[0044] In this embodiment, the horizontal groove section 211 and the inclined groove section 212 are smoothly transitioned, so that the cam follower 41 slides more smoothly between the horizontal groove section 211 and the inclined groove section 212, thereby improving the stability of the movement of the cutter holder 4.
[0045] In this embodiment, a second linear bearing is provided in the linear bearing mounting block 33, and the linear bearing mounting block 33 is slidably engaged with the second guide shaft 331 through the second linear bearing.
[0046] It should be noted that the second linear bearing is arranged in the linear bearing mounting block 33, and the second guiding shaft 331 passes through the second linear bearing. When the cam follower 41 slides between the horizontal groove section 211 and the inclined groove section 212, the second guiding shaft 331 slides relative to the linear bearing mounting block 33. The second linear bearing can make the movement process of the second guiding shaft 331 more stable, thereby improving the stability of the movement of the cutter fixing seat 4.
[0047] In this embodiment, the number of the second guiding shafts 331 is two, and the two second guiding shafts 331 are both slidably arranged on the linear bearing mounting block 33.
[0048] Two second linear bearings are arranged in the linear bearing mounting block 33, and the two second guiding shafts 331 are respectively matched with the two second linear bearings. By arranging the two second guiding shafts 331 on the linear bearing mounting block 33, the two second guiding shafts 331 jointly support the cutter fixing seat 4, further improving the stability of the movement of the cutter fixing seat 4.
[0049] It can be understood that the number of the second guiding shafts 331 can be determined according to the actual working conditions. For example, the number of the second guiding shafts 331 can also be one or more than three.
[0050] In this embodiment, the air cylinder 31 is a rodless air cylinder, and the slider of the rodless air cylinder is connected to the linear bearing mounting block 33.
[0051] Both ends of the rodless air cylinder are respectively connected to two substrates, and the slider of the rodless air cylinder is connected to the linear bearing mounting block 33. When the rodless air cylinder starts, the slider of the rodless air cylinder can drive the linear bearing mounting block 33 and the cutter fixing seat 4 and the cutter 5 on the linear bearing mounting block 33 to move synchronously.
[0052] In other embodiments, the air cylinder 31 can also be a slide table air cylinder or a guide rod air cylinder, as long as it can drive the linear bearing mounting block 33 to move.
[0053] In summary, the embodiment of the present application provides a pole piece cutting device. During the process of cutting the pole piece strip, the rodless air cylinder drives the linear bearing mounting block 33 to move along the first guiding shaft 32. The linear bearing mounting block 33 drives the cutter fixing seat 4 to move between the horizontal groove section 211 and the inclined groove section 212, and the cutter 5 moves synchronously with the cutter fixing seat 4. When the cutter 5 moves in the horizontal groove section 211, the cutter 5 cuts the pole piece strip along the width direction of the pole piece strip. Compared with the way of cutting perpendicular to the surface of the pole piece strip, it is easier to cut the pole piece strip, and the success rate of automatic roll change is improved.
[0054] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims described above.
