[0042] The first fixing platform 110 is provided with a first fixing groove 111 . The first fixing groove 111 is used to fix the battery cell 200 .

[0043] A docking port is formed at one end of the first fixing groove 111. When the battery cell 200 is placed in the first fixing groove 111, the docking port can expose a connection portion at one end of the battery cell 200, so as to facilitate welding of the connection portion with the tab 300.

[0044] The second fixing platform 120 is provided with a second fixing groove 121 ; the second fixing groove 121 is used for fixing the tab 300 .

[0045] An opening is formed at one end of the second fixing groove 121 close to the first fixing platform 110 ; the opening faces the docking port.

[0046] When the battery cell 200 is placed in the first fixing groove 111 and the tab 300 is placed in the second fixing groove 121, the end of the tab 300 close to the first fixing platform 110 can be connected to the connecting part on the battery cell 200 to position the tab 300 when welding the battery cell 200.

[0047] The pressing piece 130 has a fixed end 131 and a movable end 132; the fixed end 131 is fixed on the second fixed platform 120; the pressing piece 130 has a working state in which the movable end 132 is arranged on the second fixed platform 120, and a non-working state in which the movable end 132 is separated from the second fixed platform 120.

[0048] The pressing sheet 130 can press the tab 300 tightly into the second fixing groove 121 in the working state to prevent the tab 300 from tilting during the welding process.

[0049] The positioning fixture 100 provided in this embodiment is provided with the first fixing groove 111 on the first fixing platform 110 and the second fixing groove 121 on the second fixing platform 120. Since the opening of the second fixing groove 121 faces the docking port of the first fixing groove 111; when the battery cell 200 is fixed in the first fixing groove 111 and the tab 300 is fixed in the second fixing groove 121, one end of the tab 300 can be connected with one end of the battery cell 200 to position the tab 300 when welding the tab 300 to the battery cell 200. The pressing sheet 130 can press the tab 300 tightly into the second fixing groove 121 in the working state to prevent the tab 300 from tilting during the welding process.

[0050] Compared with the manual alignment method, the positioning fixture 100 of this embodiment positions the battery cell 200 and the tab 300, which is not only simple to operate, less dangerous, and more efficient, but also can effectively control the direction of the tab 300 to prevent the tab 300 from tilting during the welding process. The tab 300 and the battery cell 200 have a high consistency after welding, thereby greatly improving the yield rate.

[0051] See also Figure 1 and Figure 3 The shape of the first fixing groove 111 matches the shape of the battery cell 200. When the battery cell 200 is placed in the first fixing groove 111, the inner wall of the first fixing groove 111 can limit the movement of the battery cell 200.

[0052] In some embodiments, the sinking depth of the first fixing groove 111 is half of the thickness of the battery cell 200 to ensure that the inner wall of the first fixing groove 111 is capable of limiting the movement of the battery cell 200 .

[0053] In some embodiments, please refer to Figure 1 and Figure 3 The first fixing platform 110 is also provided with a taking groove 112 ; the taking groove 112 is connected to the first fixing groove 111 .

[0054] When the battery cell 200 is placed in the first fixing groove 111 , the taking groove 112 can ensure a certain distance between the battery cell 200 and the main body of the first fixing platform 110 , so that an operator can take out the battery cell 200 from the first fixing groove 111 .

[0055] In some embodiments, see Figure 4 The first fixing platform 110 is provided with two taking grooves 112 ; the two taking grooves 112 are symmetrically arranged on both sides of the first fixing platform 110 , so that the operator can take the battery cell 200 with both hands.

[0058] One end of the second fixing groove 121 in the extending direction faces the docking port on the first fixing platform 110 ; the opening is formed at one end of the second fixing groove 121 facing the docking port.

[0059] Exemplarily, the second fixing groove 121 is substantially T-shaped.

[0060] In some implementations, a plurality of second fixing grooves 121 are formed on the second fixing platform 120 so that the battery cell 200 can be positioned and connected to a plurality of the tabs 300 at the same time.

[0061] In some embodiments, see Figure 1 and Figure 2 The fixed end 131 is fixed to the second fixing platform 120 through a bolt structure.

[0065] In some embodiments, the pressing sheet 130 is an elastic pressing sheet; an operator changes the shape of the pressing sheet 130 to switch the pressing sheet 130 between the working state and the non-working state.

[0066] In some embodiments, see Figure 1 The second fixing platform 120 is fixedly connected to one end of the first fixing platform 110 close to the docking port.

[0067] Preferably, the first fixing platform 110 and the second fixing platform 120 are integrally formed.

[0068] In another embodiment, the first fixing platform 110 and the second fixing platform 120 are slidably matched, so that the relative position of the tab 300 and the battery cell 200 can be adjusted to ensure accurate positioning of the tab 300 and the battery cell 200 during welding.

[0069] Exemplarily, the positioning fixture 100 further includes a track and a slider; the track is provided on the first fixed platform 110; the slider is slidably matched with the track and connected to the second fixed platform 120. The second fixed platform 120 is slidably matched with the track through the slider, so that the second fixed platform 120 can move relative to the first fixed platform 110.
