[0022] Among them, the side baffle 3 is fixed on one side of the pole piece template 7, which plays a role in preventing the ultra-narrow pole piece 10 from laterally shifting during the positioning process, ensuring that the pole piece is in the correct position.

[0025] Specifically, the opening portion of the side push block 6 may not contact the front end surface of the extended portion of the pole piece template 7 and the inner walls on the left and right sides thereof.

[0026] In this embodiment, the shape of the tab block bar 4 can be set to be L-shaped, and the front end surface of the vertical section of the tab block bar 4 can be driven by the second push drive device 9 to contact or separate from the top end surface of the pole piece template 7.

[0027] In addition, the L-shaped structure of the tab stopper bar 4 can protect the end of the ultra-narrow pole piece 10 and avoid damaging or contaminating the tab at the extended portion of the ultra-narrow pole piece 10 during the secondary positioning process.

[0028] like Figure 3 As shown, in order to adjust the position of the side push block 6 and the bottom push block 5 relative to the pole piece template 7, the first connecting member may include a first connecting block 61 and a first adjusting block 62. The cross section of the first adjusting block 62 is L-shaped. A first adjusting hole 621 is horizontally opened on the vertical section of the first adjusting block 62 along its length direction. The back side of the side push block 6 is fixedly connected to the first adjusting hole 621 by a locking screw.

When the ultra-narrow electrode plate 10 is placed on the electrode plate template 7 by an external manipulator suction cup, due to the structural limitation of the side pushing block in an E-shaped structure and the positioning template complementarily arranged therewith, the ultra-narrow electrode plate 10 will not fall from the gap between the two. The side baffle 3 and the tab baffle 4 can perform limit resistance on one side and the top of the electrode plate template 7. Then, the first pushing driving device 8 drives the side pushing block 6 to move towards the electrode plate template 7 and contact the inner end surface of the opening groove of the electrode plate template 7. At the same time, the second pushing driving device 9 drives the bottom pushing block 5 to move towards the electrode plate template 7 and contact the bottom surface of the electrode plate template 7, so as to realize the secondary positioning of the ultra-narrow electrode plate 10.

When the ultra-narrow electrode plate is placed on the positioning template by a manipulator suction cup, it can prevent the electrode plate from falling at the gap between the side pushing block and the positioning template due to slight movement or vibration, solves the problem of gap material dropping, ensures the accuracy and precision of the secondary positioning mechanism, and thus improves the stability and production efficiency in the battery assembly process.
