[0043] As Figures 1 to 2As shown, according to the first aspect of the utility model, provide a kind of deviation rectifying device 200, comprising: first deviation rectifying component and second deviation rectifying component;First deviation rectifying component includes first mobile seat 2, first deviation rectifying roller 3 and first adjusting drive 4, first deviation rectifying roller 3 is located in first mobile seat 2, first adjusting drive 4 is configured to be able to drive first mobile seat 2 and drive first deviation rectifying roller 3 reciprocating movement along first direction;Second deviation rectifying component includes second mobile seat 14, second deviation rectifying roller 12 and second adjusting drive 13, second deviation rectifying roller 12 is located in second mobile seat 14, second adjusting drive 13 is configured to be able to drive second mobile seat 14 and drive second deviation rectifying roller 12 along first direction close or away from first deviation rectifying roller 3, first deviation rectifying roller 3 and second deviation rectifying roller 12 are parallel.

[0044] Specifically, deviation rectifying device 200 is used to make the deviation rectifying piece (hereinafter all take pole piece 28 as example) inserted between first deviation rectifying roller 3 and second deviation rectifying roller 12 be adjusted to suitable position, to facilitate the completion of next process, for example, facilitate pole piece 28 and diaphragm alignment compound as a whole.In the embodiment, by setting first deviation rectifying component, so that first adjusting drive 4 can drive first mobile seat 2 reciprocating movement along first direction, and then make first deviation rectifying roller 3 on first mobile seat 2 reciprocating movement along first direction, and the setting of second deviation rectifying component, so that second adjusting drive 13 can drive second mobile seat 14 reciprocating movement along first direction, that is, make second deviation rectifying roller 12 on second mobile seat 14 can reciprocating movement along first direction to first deviation rectifying roller 3, and then make first deviation rectifying roller 3 and second deviation rectifying roller 12 move towards or move away from each other in actual deviation rectifying process, so that first adjusting drive 4 and second adjusting drive 13 can make first deviation rectifying roller 3 and second deviation rectifying roller 12 move towards or move away from each other by driving first mobile seat 2 and second mobile seat 14 respectively, to realize the purpose of clamping pole piece 28 by first deviation rectifying roller 3 and second deviation rectifying roller 12.

[0045] In the above deviation rectifying process, taking pole piece 28 as an example, based on the fact that first deviation rectifying roller 3 and second deviation rectifying roller 12 can move away from each other and move towards each other, when the external equipment transports pole piece 28 to deviation rectifying device 200, the space between first deviation rectifying roller 3 and second deviation rectifying roller 12 can be reserved by moving them away from each other, so that the external equipment can insert pole piece 28 into the space, which not only avoids the risk of collision between the head of pole piece 28 and first deviation rectifying roller 3 or second deviation rectifying roller 12, improves the production yield of the battery, but also avoids the problem of interference between the external equipment and first deviation rectifying roller 3 or second deviation rectifying roller 12, improves the efficiency of the entire production process. When pole piece 28 is sent between first deviation rectifying roller 3 or second deviation rectifying roller 12, first adjusting drive 4 and second adjusting drive 13 can again drive first mobile seat 2 and second mobile seat 14 to move towards each other respectively, so that first deviation rectifying roller 3 and second deviation rectifying roller 12 can move close to each other to clamp pole piece 28, thereby performing the next process operation.

[0046] As can be seen from the above correction process, the correction device 200 provided by the utility model can move away from each other or move towards each other based on the first correction roller 3 and the second correction roller 12, so that the external equipment can send the pole piece 28 to the first correction roller 3 and the second correction roller 12, avoiding the problem of collision or interference between the pole piece 28 or the external equipment and the correction roller, improving the production efficiency and product yield of the equipment, and the device is simple, reducing the production cost.

[0047] The first adjustment driving member 4 and the second adjustment driving member 13 can control the position of the pole piece 28 in the first direction through the first moving seat 2 and the second moving seat 14, so that the pole piece 28 can be located at a suitable position in the first direction before being sent to the next device. The first adjustment driving member 4 and the second adjustment driving member 13 can adopt a servo motor, an electric cylinder or a pneumatic cylinder, etc. The first moving seat 2 and the second moving seat 14 can be structural members facilitating the installation and connection of the first correction roller 3, the second correction roller 12 and the first adjustment driving member 4 and the second adjustment driving member 13, and the first correction roller 3 and the second correction roller 12 are parallel to each other, which also ensures the reliability and uniformity of the clamping of the pole piece 28, further improving the correction effect of the correction device 200.
