[0002] The lithium battery cell winding machine is a very important equipment in the production of lithium batteries. Its main function is to wind the positive and negative electrode materials, diaphragms, etc. into battery cells according to the design requirements. Since the electrode sheets are prone to a certain degree of displacement error during the transmission process, they will have different degrees of deviation on the motion trajectory, resulting in the winding or truncation position to be tilted, making it impossible to meet the subsequent manufacturing process. Therefore, it is necessary to set a correction mechanism to correct the displacement error during the transmission of the electrode sheets.

[0003] At present, when using the pre-winding correction mechanism, there is a lack of an anti-scratch mechanism. Usually, when using the pre-winding correction mechanism, the correction action is achieved by pushing the pole piece. However, in actual use, due to the pushing and limiting method, it is necessary to contact the two sides of the pole piece. The friction generated can easily cause the pole piece to wear, which not only affects the accuracy of the correction, but also easily affects the winding quality and use effect. Therefore, a pre-winding correction mechanism of a fully automatic lithium battery cell winding machine is proposed to increase the anti-scratch mechanism, and use the displacement, flipping and guiding methods to drive the entire pole piece to perform sliding correction processing, avoid contact with the side of the pole piece, and cause damage to it by friction, improve the winding quality, and at the same time improve the correction efficiency, thereby improving the use effect.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] In order to facilitate the use of displacement, flipping and guiding methods to drive the entire pole piece to slide and correct deviation, thereby improving the use effect, such as Figure 1-3As shown, the pre-rolling correction mechanism of the fully automatic lithium battery cell winding machine described in the present invention includes a fixed frame 1, an active roller 2 and a correction component 5. The active roller 2 is installed in the fixed frame 1 through a bearing, and a driven roller 3 corresponding to the active roller 2 is installed on the top of the active roller 2 in the fixed frame 1 through a bearing. The outer peripheries of the active roller 2 and the driven roller 3 are both sleeved with a guide sleeve 4, and the outer peripheries of the active roller 2 and the driven roller 3 are located on both sides of the guide sleeve 4 and are sleeved with a correction component 5;

[0029] The correction component 5 includes a sliding sleeve 501, and the sliding sleeve 501 is sleeved and connected to the active roller 2 and the driven roller 3. A ball groove 502 is opened on the surface of one side of the sliding sleeve 501, and a ball 503 is rollingly connected in the ball groove 502.

[0030] During use, an anti-scratch mechanism can be added through the active roller 2, the driven roller 3, the guide sleeve 4, the sliding sleeve 501, the ball groove 502 and the ball 503, and the stability of the correction component 5 can be improved by sliding and displacement, while reducing the wear on the side of the pole piece and improving the correction quality.

[0031] In order to improve the stability of the correction, for example, Figure 1 、 Figure 2 As shown, the present invention also includes a guide groove 504 provided on one side of the ball groove 502 in the sliding sleeve 501 , and the guide groove 504 is connected to the ball groove 502 , and an opening 505 is provided on the surface of the other side of the sliding sleeve 501 , and the opening 505 is connected to the guide groove 504 .

[0032] During use, an auxiliary guide lubrication mechanism can be added through the sliding sleeve 501, the guide groove 504, and the opening 505. By pumping lubricating oil, the friction of the sliding sleeve 501 is reduced, which is beneficial to extending the service life of the correction component 5.

[0033] For example, Figure 4 As shown, the present invention also includes that the surfaces of the active roller 2 and the driven roller 3 are both provided with limiting grooves 301 , the guide sleeve 4 includes limiting ridges 401 , and the guide sleeve 4 is slidably connected to the limiting grooves 301 through the limiting ridges 401 .

[0034] When in use, the limiting groove 301 and the limiting ridge 401 facilitate the limiting sliding connection between the active roller 2 and the driven roller 3 and the guide sleeve 4 .

[0035] For example, Figure 1 As shown, both sides of the fixing frame 1 are connected with a material storage trough 6 by bolts, and the discharge ends of the material storage trough 6 are connected to the opening 505 through a hose.

[0036] During use, lubricating liquid is pumped into the opening 505 through the storage tank 6 for auxiliary lubrication. The storage tank 6 includes a delivery pump, and the discharge end of the delivery pump is connected to the opening 505 through a hose.

[0037] For example, Figure 3 As shown, the present invention further includes that a screw rod 103 is installed on the inner side of the fixing frame 1 through a bearing, and a corresponding ball slider 104 is provided on the outer sleeve of the screw rod 103, and the ball slider 104 is connected to the sliding sleeve 501 through bolts.

[0038] When in use, the ball screw 103 and the ball slider 104 can be used to control and adjust the use position of the sliding sleeve 501, thereby achieving an overall displacement correction action.

[0039] For example, Figure 1 As shown, the present invention also includes that the fixing frame 1 includes a side plate 101, the outer side of the side plate 101 is connected to the mounting plate 102 by bolts, the outer side of the side plate 101 is located at the top of the mounting plate 102 and is connected to the servo motor 7 by bolts, and the servo motor 7 is connected to the screw rod 103 through the drive shaft.

[0040] When in use, the side plate 101 and the mounting plate 102 facilitate the fixing and installation of the fixing frame 1, and the servo motor 7 facilitates the reciprocating rotation of the screw rod 103 for displacement correction adjustment. The outer side of the side plate 101 is connected to the driving motor through bolts, and the driving motor is connected to the active roller 2 through the driving shaft.

[0041] When the utility model is in use, the driving motor is first manually turned on to drive the active roller 2 to rotate, and the relative rotation of the active roller 2 and the driven roller 3 is used to make the pole piece be sent out from between the guide sleeves 4 to perform the feeding action. According to the offset range of the pole piece, the servo motor 7 is manually turned on to drive the screw rod 103 to rotate, and the ball slider 104 drives the sliding sleeve 501 to slide to one side. The sliding sleeve 501 is used to push and drive the guide sleeve 4 and the pole piece to move slowly to one side synchronously to perform the deviation correction action. The structure is simple and easy to operate, and the use is more reasonable and stable. It is also beneficial to improve the deviation correction efficiency and reduce the wear of the side edge of the pole piece by friction.

[0042] Moreover, the delivery pump can be manually started at the same time, and lubricating oil can be injected into the ball groove 502 by using the storage tank 6, the guide groove 504 and the opening 505. While lubricating the sliding sleeve 501, it can also reduce the friction with the guide sleeve 4, making it more reasonable and reliable to use, and also conducive to extending the service life of the correction mechanism.
