[0036] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1

[0038] This embodiment proposes a structure for adjusting the placement depth of pouch cells, such as... Figure 1 and Figure 2 As shown, the flexible battery cell placement depth adjustment structure is used to adjust the specific placement depth of the flexible battery cell 4 along the Z-axis downwards. This ensures the placement stability of flexible battery cells 4 of different sizes under different material matching degrees of the robotic arm 5, which is beneficial to the reliability of subsequent baking of the flexible battery cell 4. Here, the specific type of flexible battery cell 4 is not limited, and the baking principle of the flexible battery cell 4 is a common working principle in the prior art, and will not be described in detail.

[0039] It is worth noting that the different material matching degrees of the robotic arm 5 for the soft-pack battery cell 4 mentioned above specifically refer to the different gripping positions of the robotic arm 5 for different types of soft-pack battery cells 4, and the different placement positions of the soft-pack battery cells 4 along the Z-axis within the soft-pack battery cell placement depth adjustment structure; the different sizes of soft-pack battery cells 4 mentioned above specifically refer to the dimensions along the Z-axis.

[0040] Specifically, such as Figures 1 to 4 As shown, the flexible battery cell placement depth adjustment structure includes a high-temperature paper assembly 1 and an adjustment plate 2. The high-temperature paper assembly 1 includes two high-temperature papers 11 arranged opposite each other along the X-axis. The flexible battery cell 4 is gripped by a robotic arm 5 and placed downwards along the Z-axis between the two high-temperature papers 11. The adjustment plate 2 extends along the Y-axis, and adjustment plates 2 are respectively arranged on opposite sides of the high-temperature paper assembly 1 along the X-axis. The two adjustment plates 2 can be released from each other to move along the Z-axis, and the two adjustment plates 2 can be fastened together to clamp the two high-temperature papers 11, so that the high-temperature paper assembly 1 forms a V-shaped structure. The flexible battery cell 4 is placed downwards along the Z-axis within the V-shaped structure, and the bottom of the flexible battery cell 4 abuts against the clamping position between the two high-temperature papers 11. Specifically, the high-temperature paper 11 refers to paper capable of withstanding high-temperature environments, mainly made of hydroxyapatite compounds, possessing high flexibility and non-flammability, and capable of withstanding temperatures above 1000℃.

[0041] By arranging the adjusting plates 2 on the opposite sides of the high-temperature paper set 1 along the X axis and enabling the two adjusting plates 2 to be tightly connected with each other to clamp the two high-temperature papers 11, when the soft-pack battery cell 4 is placed between the two high-temperature papers 11 along the Z axis, the bottom of the soft-pack battery cell 4 abuts against the clamped position between the two high-temperature papers 11, so that the soft-pack battery cell 4 can be stably supported and shielded by the two high-temperature papers 11. On the one hand, the heat conduction efficiency of the soft-pack battery cell 4 can be ensured, and the soft-pack battery cell 4 is heated uniformly, which is beneficial to uniform baking of the soft-pack battery cell 4. On the other hand, the soft-pack battery cell 4 can be prevented from being deformed due to external pressure during baking, and the soft-pack battery cell 4 is better protected. In addition, the high-temperature paper 11 can provide insulation protection for the soft-pack battery cell 4, prevent the soft-pack battery cell 4 from directly contacting the surrounding metal structure during high-temperature baking, avoid potential short-circuit risk, and ensure high baking safety.

[0042] The soft-pack battery cell placement depth adjusting structure in the embodiment increases the two adjusting plates 2 that are clamped with the high-temperature paper set 1 in cooperation. By enabling the two adjusting plates 2 to be loosened to move along the Z axis, that is, the specific clamped positions of the two adjusting plates 2 on the high-temperature papers 11 can be adjusted according to different sizes of the soft-pack battery cell 4 and different matching degrees of the soft-pack battery cell 4 between the two high-temperature papers 11 by the mechanical hand 5, so that the clamped positions between the two high-temperature papers 11 can be adapted to different sizes of the soft-pack battery cell 4 and different matching degrees of the soft-pack battery cell 4 by the mechanical hand 5. Artificial replacement of high-temperature papers 11 of different sizes is not required, time and labor are saved, labor cost is saved, and the production efficiency of the soft-pack battery cell 4 is improved.

[0043] Further, as shown in Figures 1 to 3 The adjusting plate 2 has a length direction parallel to the length direction of the soft-pack battery cell 4 and the Y axis, and the length of the adjusting plate 2 is greater than the length of the high-temperature paper 11 along the Y axis.

[0044] By making the length of the adjusting plate 2 greater than the length of the high-temperature paper 11 along the Y axis, on the one hand, the adjusting plate 2 can completely cover the high-temperature paper 11 along the Y axis, so that the clamping effect of the adjusting plate 2 on the high-temperature paper 11 is more stable and firm. On the other hand, the fastening connection between the two adjusting plates 2 can be realized by the part of the adjusting plate 2 longer than the high-temperature paper 11, and the smooth connection between the two adjusting plates 2 is ensured.

[0045] Specifically, as shown in Figure 2 and Figure 3As shown, the adjusting plate 2 comprises a clamping part 21 and two first mounting parts 22; wherein the clamping part 21 is used to contact and clamp the high-temperature paper 11, the clamping part 21 is connected with the first mounting part 22 at opposite ends along the Y axis, the first mounting part 22 is located outside the high-temperature paper 11, and the first mounting part 22 is used to tightly connect the two adjusting plates 2 to clamp the two high-temperature papers 11.

[0046] Further, as shown in Figures 1 to 3 The clamping part 21 and the two first mounting parts 22 are integrally formed, which can better ensure the stability of the connection between the clamping part 21 and the first mounting part 22, and further ensure the stability of the clamping effect of the clamping part 21 on the high-temperature paper 11, and better ensure the support stability of the high-temperature paper group 1 on the soft package battery 4.

[0047] Specifically, as shown in Figure 2 and Figure 3 The soft package battery placement depth adjusting structure further comprises a fastener 3, and the fastener 3 is threadedly connected to the two aligned first mounting parts 22, that is, two fasteners 3 are threadedly connected between the two adjusting plates 2 to ensure that the fastening connection between the two adjusting plates 2 is stable and reliable. In the embodiment, the fastener 3 can be a bolt and a nut matched therewith.

[0048] Further, the material of the adjusting plate 2 is Teflon material, which has high chemical stability and high-temperature resistance, so as to ensure that the stability of the adjusting plate 2 is good during the process of baking the soft package battery 4, so that the adjusting plate 2 will not interfere with the baking of the soft package battery 4.

[0049] Specifically, as shown in Figures 1 to 3 Along the Y axis, the length of the high-temperature paper 11 is greater than the length of the soft package battery 4, so that the high-temperature paper 11 can completely cover the soft package battery 4 along the Y axis, so as to better provide shielding protection for the soft package battery 4, better protect the soft package battery 4, and better prevent the soft package battery 4 from directly contacting the surrounding metal structure during high-temperature baking, further ensuring the baking safety.

[0050] The soft package battery placement depth adjusting structure in the embodiment can adjust the specific clamping position of the high-temperature paper group 1 by setting the high-temperature paper group 1 and the two adjusting plates 2 in cooperation and allowing the two adjusting plates 2 to be loosened and locked with each other, and then tightly connecting the two adjusting plates 2 after moving them to the appropriate position on the high-temperature paper group 1 along the Z axis, so that the bottom of the soft package battery 1 is tightly attached to the high-temperature paper group 1 when the high-temperature paper group 1 clamps the soft package battery 4, thereby not needing to replace the high-temperature paper group 1, but only needing to move and lock the adjusting plates 2 on both sides of the high-temperature paper group 1 along the Z axis, which saves time and labor, saves labor cost, and improves the production efficiency of the soft package battery 1.
