[0031] In some embodiments, the lithium-ion battery electrode is placed on the mold platform 1 and covers the stamping hole 11. The driving member 2 and the stamping member 3 are located above the lithium-ion battery electrode. The driving member 2 drives the stamping member 3 to move downward to stamp and cut the lithium-ion battery electrode. The cut lithium-ion battery electrode falls below the stamping hole 11.

[0032] The mold platform 1 has a placement surface 12 for placing lithium-ion battery electrodes.

[0034] In some embodiments, the shape of the stamping part 3 matches the shape of the stamping hole 11, and the outer diameter of the stamping part 3 is equal to the inner diameter of the stamping hole 11.

[0035] In some embodiments, both the stamping part 3 and the stamping hole 11 are circular. The outer diameter of the stamping part 3 is equal to the inner diameter of the stamping hole 11. The stamping part 3 enters the stamping hole 11 during stamping to stamp, cut or extrude the lithium-ion battery electrode sheet.

[0036] In some embodiments, the stamped part 3 and the stamped hole 11 are irregular shapes such as rectangles and elongations, and their shapes can be designed according to actual use.

[0037] One or more stamping holes 11 are provided, and multiple stamping holes 11 are provided on the mold platform 1.

[0038] In some embodiments, the placement surface 12 is formed in the middle of the mold platform 1, and the mold platform 1 forms a U-shaped structure, through which the lithium-ion battery electrode is inserted.

[0039] like Figures 2 to 3 As shown, the mold platform 1 is divided into an upper platform 13 and a lower platform 14 by the placement surface 12, and the stamping hole 11 is divided into vertically corresponding stamping part slot hole 111 and sampling hole 112 by the placement surface 12.

[0042] In some embodiments, the shape of the stamping member slot hole 111 matches the shape of the stamping member 3.

[0043] In some embodiments, the opening end of the stamping member slot hole 111 is provided with a sealing ring, the inner diameter of the sealing ring is equal to the outer diameter of the stamping member 3, and when the stamping member 3 returns to the stamping member slot hole 111 after stamping is completed, the sealing ring can prevent the lithium ion battery from sticking to the stamping member 3, and prevent the lithium ion battery sampling pole piece from entering the stamping slot hole 111 along with the stamping member 3.

[0044] The stamping member slot hole and the sampling hole are circular holes, oval holes or polygonal holes.

[0045] As shown in Figure 2 and Figure 4 The bottom of the mold platform 1 is fixedly connected, detachably connected or movably connected with a support table 4.

[0046] In some embodiments, the support table 4 serves as a platform for supporting and bearing the mold platform 1, and the mold platform 1 is placed on the support table 4.

[0053] The collection box 5 is slidably installed below the corresponding leakage hole 43 of the table top.

[0054] In some embodiments, the four table legs 42 limit the collection box 5, thereby preventing the collection box 5 from being separated from the support table 4 due to external force collision during use.

[0055] The lithium ion battery pole piece weight sampling device will be further described in combination with the use process.

[0056] In use, the lithium ion battery pole piece is placed on the placing surface 12, the driving member 2 is started to drive the stamping member 3 to move downward to stamp and cut the lithium ion battery pole piece for sampling, the sampled pole piece falls into the collecting box 5 from the stamping hole 11 and the leakage hole 43, the collecting box 5 is pulled out, and then the sampled pole piece is weighed.
