Description

Technical Field

[0001] The utility model relates to the technical field of lithium-ion batteries, and in particular to a pole piece roll transfer vehicle. Background Art

[0002] Lithium-ion battery is a secondary battery with the advantages of high energy density, many cycles, long service life and green environmental protection. It has been widely used in electric vehicles, home appliances, smart wearables, mobile power supplies and other fields, and has become the main power source for new energy vehicles and energy storage.

[0003] As the market demand for lithium battery production capacity increases, improving the transportation efficiency of lithium-ion battery pole pieces has attracted the attention of researchers in related technical fields. In the production process of lithium batteries, pole pieces need to flow between different processes such as rolling, slitting, and winding. Therefore, a transfer vehicle is used to transport the pole rolls. A common transfer vehicle is provided with a support rod on the upper end, and the support rod is inserted into the hollow part in the center of the pole roll for lifting and transportation. However, during the transportation of the transfer vehicle, since the diameter of the hollow part of the pole roll is larger than the diameter of the support rod, the pole roll may have inertia during the turning process of the transfer vehicle, causing steering shaking, affecting the safety of the transfer vehicle's transportation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pole piece roll transfer vehicle to avoid the transfer vehicle from affecting the transportation safety of the transfer vehicle due to turning when transporting the pole roll.

[0005] Based on the technical problems existing in the background technology, the utility model proposes a pole roll transfer vehicle, including a vehicle body, a support frame and a transverse axis supporting the pole roll, wherein the transverse axis is installed on the vehicle body through the support frame, and an extrusion sheet which can expand the diameter of the transverse axis is provided on the transverse axis, and the transverse axis, the extrusion sheet and the hollow middle part of the pole roll are in conflict with each other to form a triangular stable support.

[0006] Preferably, an arc groove is provided below the horizontal axis, and two extrusion sheets are rotatably mounted on the horizontal axis and located in the arc groove. When closed, the extrusion sheets are located in the arc groove and can form a whole with the cross bar.

[0007] Preferably, a driving mechanism capable of driving the extrusion sheet to rotate is installed at the end of the transverse axis, and the rotation axis of the extrusion sheet relative to the transverse axis is parallel to the axis of the transverse axis.

[0008] Preferably, a plurality of rollable balls are embedded in the upper end of the horizontal axis.

[0009] Preferably, the vehicle body comprises a vehicle frame and a lifting plate, the lifting plate is slidably mounted on the vehicle frame, and a lifting mechanism is mounted on the vehicle frame and connected to the lifting plate.

[0010] Preferably, an X-shaped telescopic rod is hinged between the lifting plate and the frame.

[0011] Compared with the prior art, the pole piece roll transfer vehicle proposed in the present invention adopts the above technical solution and achieves the following technical effects:

[0012] When the horizontal axis in the utility model is inserted between the pole coils, the extrusion sheet is rotated to expand the maximum diameter of the horizontal axis, and the middle hollow position of the pole coil is supported at three points. The three points can form a triangular support. When the transfer vehicle turns, the pole coil is prevented from swinging on the horizontal axis, thereby increasing the stability of the transfer vehicle when turning.
