[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, a lithium-ion battery electrode assembly positioning device includes a positioning platform 1 and support legs installed at the four corners of the bottom of the positioning platform 1. Two fixing plates 2 are installed on the top of the positioning platform 1, and two mounting plates 3 are installed between the two fixing plates 2, perpendicular to the two fixing plates 2. Multiple positioning components are installed on the sides of the two mounting plates 3 that are far apart from each other. Each positioning component includes a positioning plate 4 on the top of the positioning platform 1, a limiting groove 5 formed in the mounting plate 3, a movable rod 6 slidably connected in the limiting groove 5, and a movable plate 7 installed at one end of the movable rod 6 and used in conjunction with the positioning plate 4. A T-shaped sliding groove 8 is installed on the top inner wall of the limiting groove 5, and a T-shaped slider 9 is formed on the top of the movable rod 6. The T-shaped sliding groove 8 is slidably connected to the T-shaped sliding plate 4. Inside the T-shaped slider 9, the T-shaped groove 8 and the T-shaped slider 9 can limit the movement of the moving rod 6, so that the moving rod 6 can maintain a smooth linear movement. A moving mechanism that drives multiple moving rods 6 to move is installed between the two mounting plates 3. The moving mechanism includes a push rod 10, multiple fixed blocks 11 installed on both sides of the push rod 10, and connecting rods 12 hinged to the top of the multiple fixed blocks 11. One end of the multiple connecting rods 12 is respectively hinged to the end of the multiple moving rods 6 away from the moving plate 7. One side of one of the fixed plates 2 has an installation opening. An installation box 13 is installed inside the installation opening. A pneumatic cylinder 14 is installed on the inner wall of one side of the installation box 13. The output end of the pneumatic cylinder 14 is fixedly connected to one side of the push rod 10.

[0022] It should be noted that, in use, this lithium-ion battery electrode positioning device can place multiple lithium-ion battery electrode groups on one side of multiple positioning plates 4. After placement, the pneumatic cylinder 14 will extend, thereby driving the push rod 10 to move. Under the action of the push rod 10, multiple fixing blocks 11 will move. Under the action of the fixing blocks 11, the connecting rod 12 will push the moving rod 6 to move. Under the action of the moving rod 6, the moving plate 7 will move closer to the positioning plate 4, thereby fixing the lithium-ion battery electrode group between the moving plate 7 and the positioning plate 4. This can meet the requirement of fixing multiple lithium-ion battery electrode groups at the same time.

[0023] Example 2

[0024] like Figure 2 and Figure 5 As shown, the difference between this embodiment and embodiment 1 is that: the top of the positioning platform 1 is provided with a strip-shaped opening 15, and the bottom of the positioning plate 4 is provided with a positioning block 16 that passes through the strip-shaped opening 15 and extends to the bottom of the positioning platform 1. The positioning block 16 has an L-shaped structure, and the bent top surface of the positioning block 16 slides and fits against the bottom surface of the positioning platform 1. The bottom of the positioning platform 1 is provided with a fixing mechanism for fixing the positioning block 16. The fixing mechanism includes a positioning bolt 18, a plurality of first positioning holes 17 opened at the bottom of the positioning platform 1 and along the direction of the strip-shaped opening 15 and used in conjunction with the positioning bolt 18, and a second positioning hole 19 opened on the positioning block 16 and used in conjunction with the first positioning holes 17 and the positioning bolt 18.

[0025] The further improvement of this embodiment is that the position of the positioning plate 4 can be adjusted according to the model of the lithium-ion battery electrode group during use. When the position of the positioning plate 4 needs to be adjusted, the positioning bolt 18 can be unscrewed from one of the first positioning holes 17, and then the positioning plate 4 can be moved along the direction of the strip opening 15. At this time, the positioning block 16 will move inside the strip opening 15. After the position of the positioning plate 4 is adjusted, the positioning bolt 18 can be screwed back into the other first positioning hole 17 to fix the positioning block 16, thereby fixing the positioning plate 4. In this way, when fixing multiple lithium-ion battery electrode groups, the need to fix lithium-ion battery electrode groups of different specifications and sizes at the same time can be met, which improves the versatility of the positioning device.

[0026] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
