Description

Technical Field

[0001] The utility model belongs to the technical field of laminators, and particularly relates to a high-speed electrode sheet transfer device and a high-speed laminator. Background Art

[0002] At present, in the manufacturing process of large lithium-ion power batteries, a laminator is usually used to perform Z-shaped lamination assembly on the positive and negative electrode sheets and the separator film of the lithium-ion battery electrode sheets to manufacture electrode sheets.

[0003] Refer to Figure 6 , the existing laminator generally includes a positive electrode material box 200, a negative electrode material box 300, a positive electrode positioning table 220, a negative electrode positioning table 320, a positive electrode material taking manipulator 230, a negative electrode material taking manipulator 330, a positive electrode laminating manipulator 240, a negative electrode laminating manipulator 340, and a laminating table 400. During lamination, the positive electrode material taking manipulator 230 and the negative electrode material taking manipulator 330 respectively suck the positive electrode sheet in the positive electrode material box 200 and the negative electrode sheet in the negative electrode material box 300, and place the positive electrode sheet and the negative electrode sheet on the positive electrode positioning table 230 and the negative electrode positioning table 330 for positioning respectively. The positioning method usually uses a CCD camera for photographing and positioning. After positioning, the positive electrode laminating manipulator 240 and the negative electrode laminating manipulator 340 respectively suck the positive electrode sheet on the positive electrode positioning table 230 and the negative electrode sheet on the negative electrode positioning table 330, and alternately laminate the positive electrode sheet and the negative electrode sheet on the laminating table 400. The laminating table 400 moves left and right in cooperation with the actions of the positive electrode laminating manipulator 240 and the negative electrode laminating manipulator 340, and forms a Z shape with the separator film to separate the positive and negative electrode sheets. Such cyclic actions realize the lamination assembly of the electrode group.

[0004] In the actual use process, since the electrode sheets (positive electrode sheets or negative electrode sheets) are stacked in the material box, there will be an adhesion phenomenon between the upper and lower layers of electrode sheets in the material box. Therefore, after the electrode sheet material taking manipulator sucks the topmost electrode sheet in the material box, the lower layer of electrode sheets is usually separated from the upper layer of electrode sheets by shaking up and down, which solves the problem of double sheets in the material taking of the electrode sheet material taking manipulator, and is therefore widely used in laminators. However, since the electrode sheet material taking manipulator needs to consume a certain amount of operation time when shaking the sheets, the time for the electrode taking manipulator to suck the electrode sheet from the material box, shake the sheets, and then transfer it to the electrode positioning table is longer than the time for the laminating manipulator to stack the electrode sheet on the positioning table onto the laminating table, resulting in the lamination speed of the laminator unable to be further increased.

[0040] Compared with the prior art, at least one of the above one or more technical solutions in the high-speed pole piece transfer device 100 provided by the embodiment of the present invention has the following technical effects:

After the shaking operation is completed, the first X-direction transfer component 121 and the first Z-direction transfer component 122 drive the first material taking component 125 to transfer the pole piece to the next station (for example: the transfer table or the positioning table). At the same time, the second X-direction transfer component 131 and the second Z-direction transfer component 132 drive the second material taking component 135 to return to the material box and suck the pole piece in the material box and perform the shaking operation.

[0045] In some embodiments, referring to Figures 1 - 3 , after the first picking component 125 picks up the pole piece, the first Z-direction transfer component 122 can drive the first picking component 125 to reciprocate up and down, generating vibration for the pole piece to achieve shaking the piece. Similarly, after the second picking component 135 picks up the pole piece, the second Z-direction transfer component 132 can drive the second picking component 135 to reciprocate up and down, generating vibration for the pole piece to achieve shaking the piece.

[0046] In another embodiment, the first picking component 125 includes a plurality of first shaking members and a plurality of first suction cups. The plurality of first shaking members are evenly arranged on the first horizontal mounting plate 124, and the plurality of first suction cups are respectively arranged on the plurality of first shaking members. The first shaking members are used to drive the first suction cups to reciprocate up and down. Specifically, after the plurality of first suction cups pick up the pole piece, the first shaking members drive the first suction cups to reciprocate up and down, generating vibration for the pole piece to achieve shaking the piece.

[0049] Further, referring to Figures 1 - 3 , both the first moving frame 123 and the second moving frame 133 are L-shaped, and the horizontal part of the first moving frame 123 and the horizontal part of the second moving frame 133 are arranged one above the other. The vertical part of the first moving frame 123 is installed on the first Z-direction transfer component 122, and the first horizontal mounting plate 124 is arranged on the horizontal part of the first moving frame 123, which is convenient for installing the first horizontal mounting plate 124. The vertical part of the second moving frame 133 is installed on the second Z-direction transfer component 132, and the second horizontal mounting plate 134 is arranged on the horizontal part of the second moving frame 133, which is convenient for installing the second horizontal mounting plate 134.

[0050] Further, referring to Figures 1 - 3 , the first X-direction transfer component 121 and the second X-direction transfer component 131 are linear modules or rodless cylinders.
