[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 The utility model provides a battery pole sheet rolling device, comprising:
[0021] The arc roller 100 has end shafts 101 at both ends, and the end shafts 101 are inserted into the roller frame 200;
[0022] The horizontal adjustment mechanism is arranged on the roller frame 200 and connected to the end shaft 101, and is used to adjust the shape of the arc roller 100 according to the shape of the battery pole piece;
[0023] The vertical adjustment mechanism is connected to the roller frame 200 and is used to adjust the pressure of the arc roller 100 on the battery electrode.
[0024] In this embodiment, a variable-shaped arc roller 100 is provided, and the shape of the arc roller 100 is adjusted in real time according to the shape of the battery pole piece by a horizontal adjustment mechanism, and the pressure of the arc roller 100 on the battery pole piece is adjusted in real time according to the required rolling pressure by a vertical adjustment mechanism, so as to achieve a better rolling effect, avoid the tedious operation of frequently replacing the pressure roller, reduce the difficulty of production operation, thereby improving efficiency and saving production time.
[0025] In one embodiment, the arc roller 100 is a rubber roller. Specifically, nitrile rubber can be used. This embodiment is configured so that the arc roller 100 has deformation capability and can adapt to the shape of the battery pole piece under the drive of external force, thereby achieving a better rolling effect.
[0026] In one embodiment, the horizontal adjustment mechanism includes an adjusting screw 300 , the adjusting screw 300 is threadedly passed through the roller frame 200 , and an end portion thereof is rotatably connected to the arc roller 100 .
[0027] The present embodiment is configured such that the arc roller 100 is squeezed by screwing the adjusting screw 300 into the roller frame 200 to increase its own bending curvature, and the adjusting screw 300 is screwed outward to reduce the force acting on the arc roller 100, so that the arc roller 100's own bending curvature becomes smaller, thereby controlling the shape of the arc roller 100, so as to quickly adapt to the replaced battery pole piece and improve the quality and efficiency of rolling.
[0028] In one embodiment, the vertical adjustment mechanism is a driving cylinder 400 .
[0029] In one embodiment, a pressure regulating mechanism 500 is disposed on the roller frame 200 . The pressure regulating mechanism 500 is movably disposed on the roller frame 200 and is used to adjust the local pressure of the arc roller 100 .
[0030] This embodiment is configured such that the local pressure on the arc roller 100 is precisely adjusted by the movable pressure regulating mechanism 500, so as to provide the required rolling force for the battery pole piece.
[0031] In one embodiment, the pressure regulating mechanism 500 includes a spherical pressure block 501, which is located on the same vertical plane as the arc roller 100, and is connected to an adjusting cylinder 502, which is mounted on a slider 503, which is slidably matched with a slide groove provided on the roller frame 200, and which is controlled to move by a driving mechanism 504. The driving mechanism 504 may be a linear motor; the surface of the spherical pressure block 501 is a rough surface or is covered with an anti-slip sleeve to ensure friction when in contact with the arc roller 100 and prevent sliding.
[0032] This embodiment is configured such that when additional adjustment of the local pressure of the arc roller 100 is required, the driving mechanism 504 controls the slider 503 to drive the spherical pressure block 501 to move to just above the specified position of the arc roller 100, and the spherical pressure block 501 is controlled by adjusting the cylinder 502 to move downward and contact the arc roller 100, thereby providing more precise local roller pressure and improving the rolling effect and quality.
