The shaping component 14 of this embodiment is provided with a detachably connected shaping wheel assembly and / or guide disc assembly.

[0042] The shaping assembly 14 includes a shaping wheel mounting frame 141, a first deflection device 142, a second deflection device 143 and a shaping wheel assembly, and the shaping wheel assembly includes a first shaping wheel 144 and a second shaping wheel 145. The shaping wheel mounting frame 141 is fixedly connected to the limit block 16, the first deflection device 142 and the second deflection device 143 are mounted on the shaping wheel mounting frame 141, the first shaping wheel 144 is transmission-connected to the first deflection device 142, and the second shaping wheel 145 is transmission-connected to the second deflection device 143. Preferably, the first shaping wheel 144 and the second shaping wheel 145 are both conical structures, wherein a conical side surface 1441 is provided on the conical structure. In addition, the first deflection device 142 and the second deflection device 143 of the present embodiment both include a mounting plate 1421 mounted on the truing wheel mounting frame 141 and having an axial rotation axis, a gear 1422 mounted on the mounting plate 1421, and a rack 1423 meshed with the gear 1422 and connected to the driving shaft. When the driving shaft moves in the horizontal direction, the rack 1423 will be driven to move, and the rack 1423 will drive the gear 1422 meshed with the rack 1423 to rotate, thereby driving the mounting plate 1421 to rotate, wherein the first truing wheel 144 / the second truing wheel 145 are mounted on the mounting plate 1421, and the angle of the first truing wheel 144 / the second truing wheel 145 can be adjusted while the mounting plate 1421 rotates, so that the tapered side surface 1441 is adjusted to different angles.

[0043] Specifically, the first driving device 11 drives the rotating device 12 to perform a lateral movement in the horizontal direction, thereby driving the driving shaft and the driving tube sleeved on the outside of the driving shaft to move in the horizontal direction, thereby driving the limit block 16 and the shaping component 14 fixedly connected to the limit block 16 to perform a lateral movement in the horizontal direction. When moved into place, the limit block 16 will abut against the blocking device 15, so that the shaping wheel mounting frame 141 cannot move in the horizontal direction. Preferably, this embodiment also preferably includes a fixed frame 8 mounted on the frame, wherein the fixed frame 8 is provided with a through hole, and the driving tube slides in the through hole, thereby improving the linear motion accuracy of the shaping component 14 of this embodiment. This embodiment is also preferably provided with a spring device sleeved on the driving tube and located between the fixed frame 8 and the limit block 16, thereby improving the stability between the limit block 16 and the fixed frame 8. Next, the driving rack 1423 of the driving shaft moves forward and backward, driving the gear 1422 to rotate, thereby driving the mounting plate 1421 to rotate, and the first shaping wheel 144 / the second shaping wheel 145 are mounted on the mounting plate 1421.

[0044] In this embodiment, a driving tube is sleeved on the outer side of the driving shaft of the rotating device 12, and a limit block 16 is set on the driving tube and a blocking device 15 is set on the frame. This is so that after the driving shaft drives the driving tube and the shaping component 14 to move into place, the blocking device 15 blocks the limit block 16 in the horizontal direction, so that the shaping wheel mounting frame 141 is relatively fixed in the horizontal direction. At this time, the driving shaft can continue to move in the horizontal direction, so as to control the movement of the rack 1423 and then control the angle of the first shaping wheel 144 and the second shaping wheel 145. The structure is ingenious. One driving device can control the movement of the shaping component 14 and the angle of the shaping wheel. There is no need to add additional driving devices or polarization devices to adjust the angles of the first shaping wheel 144 and the second shaping wheel 145. The equipment cost is lower, the structure is compact, and the weight is lighter.

[0045] This embodiment also preferably includes a second shaping mechanism 2 mounted on the frame, wherein the second shaping mechanism 2 has the same structure as the first shaping mechanism 1, and the second shaping mechanism 2 is spaced away from or close to the first shaping mechanism 1 in the horizontal direction.

[0046] As a preferred embodiment, the present embodiment also preferably includes a guide rail 3, a first slide plate 4, a second slide plate 5, a third drive device 6 and a fourth drive device 7.

The first shaping mechanism 1 is mounted on the first slide plate 4, and the second shaping mechanism 2 is mounted on the second slide plate 5. Specifically, the third drive device 6 drives the first slide plate 4 to move in the horizontal direction, thereby driving the first shaping mechanism 1 to move in the horizontal direction, and the fourth drive device 7 drives the second slide plate 5 to move in the horizontal direction, thereby driving the second shaping mechanism 2 to move in the horizontal direction, so that the first shaping mechanism 1 and the second shaping mechanism 2 can be close to or away from each other in the horizontal direction, so that the first shaping mechanism 1 and the second shaping mechanism 2 can shape the positive pole ear and the negative pole ear (one side of the two ends of the cylindrical battery cell is positive and the other side is negative) of the battery cell at the same time, thereby improving the shaping efficiency.

[0047] Preferably, the present embodiment further includes a handle micrometer assembly installed on the output shafts of the third drive device 6 and the fourth drive device 7, and a push rod transmission-connected to the handle micrometer assembly, and the second slide plate 5 and the first slide plate 4 are respectively transmission-connected to the push rod, so that during the shaping operation, the handle micrometer assembly can be manually adjusted to adjust the extension length of the push rod, and then the moving distance of the first slide plate 4 or the second slide plate 5 can be adjusted, and then the position distance of the first shaping wheel 144 or the second shaping wheel 145 relative to the battery cell pole ear can be adjusted, so that the shaping operation of the battery cell can be better controlled and the accuracy of the shaping work of the present embodiment can be improved.

[0048] Embodiment 2

[0049] like Figure 3-Figure 8 As shown, this embodiment provides another battery tab shaping device, wherein the guide plate assembly includes a first guide plate 1461, a second guide plate 1462 and a third guide plate 1463 which are detachably connected, and the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463 are detachably mounted on a guide plate mounting frame 146, and the side surfaces of the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463 are provided with a conical groove which is concave inwardly with the center of the circle as the vertex to form a guide end surface 1464 for tab shaping, and the remaining structure is the same as that of the first embodiment and will not be repeated.

[0050] The guide end faces 1464 on the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463 of this embodiment respectively form guide angles with the outer side faces of the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463, and the angle of the guide angle of the first guide plate 1461 is greater than the angle of the guide angle of the second guide plate 1462 and the angle of the guide angle of the third guide plate 1463. Preferably, the guide angle of the first guide plate 1461 is 110°, the guide angle of the second guide plate 1462 is 100°, and the guide angle of the third guide plate 1463 is 90°.

[0051] Specifically, the first driving device 11 drives the rotating device 12 to perform a lateral movement in the horizontal direction, thereby driving the driving shaft and the driving tube sleeved on the outside of the driving shaft to move in the horizontal direction, thereby driving the limit block 16 and the shaping assembly 14 fixedly connected to the limit block 16 to perform a lateral movement in the horizontal direction. When the limit block 16 is moved into position, it will abut against the blocking device 15, so that the guide disk mounting frame 146 cannot move in the horizontal direction. Then, the driving shaft drives the first guide disk 1461 to move, so that the guide end surface 1464 of the first guide disk 1461 fits on the pole ear of the pole ear winding core, and then the rotating device 12 drives the first guide disk 1461 to rotate, and the first guide disk 1461 can flatten and shape the pole ear direction, and then the first guide disk 1461 is replaced with the second guide disk 1462, and the driving shaft drives the second guide disk 1462 to move, so that the guide end surface 1464 of the second guide disk 1462 fits on the pole ear of the pole ear winding core. Then, the rotating device 12 drives the second guide plate 1462 to rotate, and the second guide plate 1462 can flatten and shape the direction of the pole ear. Then, the second guide plate 1462 is replaced with the third guide plate 1463, and then the driving shaft drives the third guide plate 1463 to move, so that the guide end surface 1464 of the third guide plate 1463 is attached to the pole ear of the cut pole ear winding core, and then the rotating device 12 drives the third guide plate 1463 to rotate, and the third guide plate 1463 can flatten and shape the direction of the pole ear. In this embodiment, the direction of the pole ear is shaped by the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463, so as to ensure the direction of each pole ear after die-cutting. In addition, since the pole ear of the battery cell needs to be pressed and flattened, a gradual transition of angles needs to be achieved during the shaping process. Therefore, the guide end faces 1464 of the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463 of this embodiment form different guide angles with the outer side surfaces of the first guide plate 1461, the second guide plate 1462 and the third guide plate 1463, and the guide angle of the first guide plate 1461 is greater than the guide angle of the second guide plate 1462 and the guide angle of the third guide plate 1463. In this way, during the shaping process of the pole ear, the use of the guide plates is replaced according to the angle, and the first guide plate 1461 is used first, then the second guide plate 1462, and finally the third guide plate 1463, to achieve a gradual transition of angles until the guide plate makes the surface of the battery cell pole ear 180°.

[0052] The guide end face 1464 of the present embodiment is formed by being recessed inwardly with the center of the circle on the side of the first guide plate 1461 / the second guide plate 1462 / the third guide plate 1463 as the vertex. In this way, during the shaping process, as long as the first guide plate 1461 / the second guide plate 1462 / the third guide plate 1463 is rotated, the guide end face 1464 can continue to shape the pole ear. When the shaping angle is appropriate, the guide plate with another guide angle can be replaced.
