[0038] Example 1

[0039] See also Figure 1This embodiment provides a material unloading support device 100. The material unloading support device 100 provided in this embodiment is mainly used to solve the problem of the internal separator of the prismatic battery core 200 being unsupported after winding, so that the body and the separator can be pressed tightly, thereby improving the yield rate of the core 200. The core 200 includes a body and a separator, and the outer side of the separator is in contact with the inner side of the body.

[0040] In this embodiment, the diaphragm is a substantially elliptical hollow structure, and the blanking support assembly 110 extends into the diaphragm to support the diaphragm when the winding needle is withdrawn from the diaphragm.

[0041] See also Figure 1-Figure 3 In this embodiment, the blanking support device 100 includes a support assembly 110 and a support plate assembly 120, and the support assembly 110 is disposed on the support plate assembly 120;

[0042] The support plate assembly 120 is used to drive the support assembly 110 to move to the winding core 200;

[0043] The support assembly 110 is used to extend into the diaphragm to fit the diaphragm and the body.

[0044] In this embodiment, the pallet assembly 120 drives the support assembly 110 to move to the main body, and the support assembly 110 extends into the diaphragm to support the diaphragm so that the diaphragm and the main body can always remain in contact. When pressing the core, the main body and the diaphragm can be pressed tightly, thereby improving the yield of the core 200.

[0045] See also Figure 4 In this embodiment, the support assembly 110 includes a driving assembly 112 and a positioning assembly 114 . The driving assembly 112 is mounted on the support plate assembly 120 , and the positioning assembly 114 is connected to the driving assembly 112 .

[0046] In this embodiment, the driving component 112 is installed on the pallet component 120, and the pallet component 120 drives the support component 110 to move toward the direction close to the core 200. When the pallet component 120 contacts the outer surface of the main body, the support component 110 extends into the fixed diaphragm to keep the diaphragm and the main body in contact. The diaphragm falls off from the main body, resulting in the body and the diaphragm being unable to be pressed tightly, and black spots, decomposition and other phenomena appearing during formation.

[0047] In this embodiment, the driving assembly 112 includes a lifting driving portion 1122 and a translation driving portion 1124. One end of the lifting driving portion 1122 is connected to the support plate assembly 120, and the other end is connected to the translation driving portion 1124. The translation driving portion 1124 is connected to the positioning assembly 114.

[0048] The lifting drive unit 1122 is used to drive the positioning assembly 114 to move to the diaphragm through the translation drive unit 1124;

[0049] The translation drive unit 1124 is used to drive the positioning assembly 114 to extend into the diaphragm to position the diaphragm.

[0050] In this embodiment, when the support plate assembly 120 moves to contact the outside of the main body, the lifting drive unit 1122 moves the positioning assembly 114 to the diaphragm through the translation drive unit 1124. The translation drive unit 1124 drives the positioning assembly 114 into the diaphragm to position the diaphragm so that the diaphragm can always remain in contact with the main body.

[0051] In this embodiment, the lifting driving part 1122 is a cylinder.

[0052] It should be noted that, in this embodiment, the lifting drive part 1122 is a cylinder, but is not limited to this. In other embodiments of the present invention, the lifting drive part 1122 can also be a motor. Solutions equivalent to this embodiment that can achieve the effects of this embodiment are within the scope of protection of the present invention.

[0053] In this embodiment, the translation driving portion 1124 is a cylinder.

[0054] It should be noted that, in this embodiment, the translation drive unit 1124 is a cylinder, but is not limited to this. In other embodiments of the present invention, the translation drive unit 1124 can also be a motor. Solutions equivalent to this embodiment that can achieve the effects of this embodiment are within the scope of protection of the present invention.

[0055] In this embodiment, the positioning assembly 114 includes a plurality of positioning members 1142 , and the plurality of positioning members 1142 are all connected to the driving assembly 112 . The driving assembly 112 drives the positioning members 1142 to extend into the diaphragm, supports the diaphragm, and makes the diaphragm fit with the body.

[0056] See also Figure 5 In this embodiment, the positioning member 1142 includes a positioning portion 1144 and an exhaust pipe 1146. The positioning portion 1144 is provided with a plurality of through holes 1148. The exhaust pipe 1146 is provided in the positioning portion 1144. The exhaust pipe 1146 is connected to the through holes 1148 and blows air toward the diaphragm through the through holes 1148 to make the diaphragm fit with the body.

[0057] In this embodiment, the exhaust pipes 1146 are connected to multiple through holes 1148. When the positioning portion 1144 extends into the diaphragm and fits with the diaphragm, the exhaust pipes 1146 blow air into the diaphragm through the through holes 1148, so that the diaphragm can remain in fit with the body.

[0058] In this embodiment, the plurality of through holes 1148 extend along the extension direction of the body.

[0059] See also Figure 6In this embodiment, the pallet assembly 120 includes a pallet 122 and a pallet driving member 124 . The pallet driving member 124 is connected to the pallet 122 , and the support assembly 110 is installed on the pallet 122 .

[0060] In this embodiment, the support plate driving member 124 drives the support plate 122 to move toward the diaphragm. When the support plate 122 contacts the body, the support plate driving member 124 stops working.

[0061] In this embodiment, the support plate assembly 120 further includes a positioning block 126 . The positioning block 126 is mounted on the support plate 122 . The positioning block 126 can abut against a side of the body away from the support assembly 110 .

[0062] In this embodiment, the positioning block 126 abuts against a side of the body away from the support assembly 110 , so that the positioning portion 1144 can position the body when it extends into the diaphragm.

[0063] In this embodiment, the support plate driving member 124 is a cylinder.

[0064] It should be noted that in this embodiment, the pallet driving member 124 is a cylinder, but is not limited to this. In other embodiments of the present invention, the pallet driving member 124 can also be a motor. Solutions equivalent to this embodiment that can achieve the effects of this embodiment are within the scope of protection of the present invention.
