[0033] In this embodiment, the pressing blade assembly 120 is arranged on the side of the lamination table 130 in the first direction X. The lifting assembly 110 drives the pressing blade assembly 120 to move in a direction closer to or away from the lamination table 130, so that the pressing blade assembly 120 fixes the pole piece placed on the lamination table 130. In this implementation, the pressing blade assembly 120 is arranged at an angle to the extending direction of the lamination table 130 in the first direction X, that is, the pressing blade assembly 120 is arranged on the side of the lamination table 130, enabling the pressing blade assembly 120 to fix the pole piece from the side of the lamination table 130, which can reduce the length of the pressing blade assembly 120, enhance the rigidity of the pressing blade assembly 120, and improve the service life of the lamination device 100.

[0034] In this embodiment, the lamination table 130 is generally rectangular, the first direction X is the length direction of the lamination table 130, and the second direction Y is the width direction of the lamination table 130. That is to say, the pressing blade assembly 120 is arranged on one side of the long side of the lamination table 130.

[0035] In this embodiment, the lifting assembly 110 includes a first lifting member 114, a second lifting member 115 and a fixing member 112. The first lifting member 114 is arranged on the side of the lamination table 130 away from the pressing blade assembly 120 in the third direction Z. The fixing member 112 connects the first lifting member 114 and the pressing blade assembly 120. The second lifting member 115 is in transmission connection with the pressing blade assembly 120;

[0036] The first lifting member 114 is used to drive the pressing blade assembly 120 to move closer to or away from the lamination table 130 in the first direction X through the fixing member 112 and the second lifting member 115;

[0037] The second lifting member 115 is used to drive the pressing blade assembly 120 to move closer to or away from the lamination table 130 in the third direction Z;

The first sliding groove 1162 cooperates with the first sliding rail 1172, and the first sliding groove 1162 and the first sliding rail 1172 extend along the third direction Z.

[0044] In this embodiment, the second sliding member 117 is fixed on the fixed member 112, and the first sliding member 116 is fixed to the pressing knife assembly 120. When the second lifting member 115 drives the pressing knife assembly 120 to move in the third direction Z, the first slide rail 1172 slides in the third direction Z relative to the first slide groove 1162, causing the pressing knife assembly 120 to move in a direction close to the stacking table 130.

[0045] In this embodiment, the fixing member 112 includes a connecting portion 1122 and a mounting portion 1124 which are connected to each other. The connecting portion 1122 is fixedly connected to the first lifting member 114 , and the mounting portion 1124 is detachably connected to the first sliding member 116 .

[0046] In this embodiment, the mounting portion 1124 extends along the second direction Y.

[0047] In this embodiment, the first sliding member 116 is detachably connected to the mounting portion 1124, and the position of the knife pressing assembly 120 relative to the lamination table 130 in the second direction Y can be adjusted according to actual conditions. The position of the knife pressing assembly 120 can be adjusted according to the actual length of the pole piece, so that the knife pressing assembly 120 can fix the pole piece placed on the lamination table 130.

[0048] In this embodiment, the lifting assembly 110 further includes a mounting member, and the mounting portion 1124 is provided with a fixing groove 1126 along the second direction Y. The mounting member passes through the fixing groove 1126 and is detachably fixed to the first sliding member 116 .

[0049] In this embodiment, the fixing groove 1126 is strip-shaped and extends along the second direction Y. The first sliding member 116 can adjust its position relative to the stacking table 130 within the fixing groove 1126, so that the pressing blade assembly 120 can adjust its position relative to the stacking table 130 in the second direction Y.

[0050] In this embodiment, the first lifting member 114 is a servo motor. Driving with a servo motor can precisely control the movement position of the pressing blade assembly 120, improve the movement speed of the pressing blade assembly 120, and thus improve the stacking efficiency.

[0051] In this embodiment, the second lifting member 115 is a servo motor. Driving with a servo motor can precisely control the movement position of the pressing blade assembly 120, improve the movement speed of the pressing blade assembly 120, and thus improve the stacking efficiency.

[0052] In this embodiment, the lifting assembly 110 further includes a third sliding member 118 and a fourth sliding member 119. The third sliding member 118 is fixedly connected to the first lifting member 114, the fourth sliding member 119 is fixed to the stacking table 130. A second sliding groove 1182 is provided on the third sliding member 118, and a second sliding rail 1192 is provided on the fourth sliding member 119. The second sliding groove 1182 cooperates with the second sliding rail 1192, and the second sliding groove 1182 and the second sliding rail 1192 extend along the third direction Z.

[0053] In this embodiment, when the second lifting member 115 drives the pressing blade assembly 120 to move closer to or away from the stacking table 130 in the third direction Z, the second sliding rail 1192 can move slightly relative to the second sliding groove 1182 to adjust the position of the first lifting member 114.

[0054] In this embodiment, the pressing blade assembly 120 includes a fixing plate 122 and a pressing blade 124. The fixing plate 122 is detachably connected to the fixing member 112. The pressing blade 124 is disposed at one end of the fixing plate 122 away from the second lifting member 115 in the third direction Z. The second lifting member 115 is connected to the fixing plate 122. The pressing blade 124 is used to fix the pole piece placed on the stacking table 130.

[0055] In this embodiment, disposing the pressing blade 124 on one side of the stacking table 130 in the first direction X can reduce the length of the pressing blade 124, enhance the rigidity of the pressing blade 124, and improve the service life of the stacking device 100.

[0056] It should be noted that two stacking devices 100 can be provided simultaneously. When the pole pieces on one stacking device 100 are accumulated and completed, during the unloading process, the other stacking device 100 can be used for stacking. The two stacking devices 100 work alternately to achieve continuous stacking of the pole pieces, greatly improving the stacking efficiency.

[0057] Working principle of the lamination device 100 provided in this embodiment: In this embodiment, an external manipulator places the electrode sheet on the lamination table 130. The first lifting member 114 drives the pressing blade member 124 to move in the first direction X towards the lamination table 130, so that the pressing blade member 124 is located directly above the electrode sheet. The second lifting member 115 drives the pressing blade member 124 to move in the third direction Z towards the lamination table 130, so that the pressing blade member 124 fixes the electrode sheet. When the manipulator needs to place the next electrode sheet, the second lifting member 115 drives the pressing blade member 124 to move in the third direction Z away from the lamination table 130, and the first lifting member 114 drives the pressing blade member 124 to move in the first direction X away from the lamination table 130. By repeating the above process, the stacking of the electrode sheets is achieved.

[0058] In summary, for the lamination device 100 provided in this embodiment, in this embodiment, the pressing blade assembly 120 is arranged on the side of the lamination table 130 in the first direction X. The lifting assembly 110 drives the pressing blade assembly 120 to move towards or away from the lamination table 130, so that the pressing blade assembly 120 fixes the electrode sheet placed on the lamination table 130. In this implementation, the pressing blade assembly 120 is arranged in the first direction X at an angle to the extending direction of the lamination table 130, that is, the pressing blade assembly 120 is arranged on the side of the lamination table 130, so that the pressing blade assembly 120 can fix the electrode sheet from the side of the lamination table 130, which can reduce the length of the pressing blade assembly 120, enhance the rigidity of the pressing blade assembly 120, and improve the service life of the lamination device 100.
