[0053] As Figure 1 and Figure 2 shown, an embodiment of the present application provides a pole piece roller feeding and deviation correcting device 100, which is mainly applied to winding equipment. The pole piece roller feeding and deviation correcting device 100 includes a first frame 110, a first sliding frame 120, a first linear module 131, a first conveying roller 1322, a first driving member 1321, a first detection sensor 141, and a controller (not shown in the figure).

[0054] The first sliding carriage 120 is slidably connected to the first frame 110. A first linear module 131 is disposed on the first frame 110. The output end of the first linear module 131 is connected to the first sliding carriage 120 and is configured to drive the first sliding carriage 120 to linearly slide reciprocally relative to the first frame 110 along the first direction Y. A first conveying roller 1322 is rotatably disposed on the first sliding carriage 120 and is used for conveying the electrode sheet. A first driving member 1321 is disposed on the first sliding carriage 120. The output end of the first driving member 1321 is connected to the first conveying roller 1322 and is used for driving the first conveying roller 1322 to rotate so as to convey the electrode sheet.

[0055] A first detection sensor 141 is disposed on the first frame 110 and is oriented towards the first conveying roller 1322, and is used for detecting whether the electrode sheet at the first conveying roller 1322 deviates from a preset position along the first direction Y. The controller is electrically connected to the first detection sensor 141 and the first linear module 131 respectively, and is also electrically connected to the first driving member 1321.

[0056] For the electrode sheet roller feeding and deviation correction device 100 provided by the embodiment of the present application, when the electrode sheet at the first conveying roller 1322 deviates from the preset position along the first direction Y, the first detection sensor 141 disposed on the first frame 110 feeds back a deviation signal to the controller. The controller controls the output end of the first linear module 131 to move in a direction away from the first direction Y according to the deviation signal fed back by the first detection sensor 141, so as to drive the first sliding carriage 120 to synchronously slide relative to the first frame 110 in a direction away from the first direction Y, thereby causing the first conveying roller 1322 and the first driving member 1321 disposed on the first sliding carriage 120 to synchronously slide relative to the first frame 110 in a direction away from the first direction Y, and further driving the electrode sheet to move in a direction away from the first direction Y to return to the preset position, thereby realizing the deviation correction function of the electrode sheet and ensuring the position accuracy of the electrode sheet. At the same time, by electrically connecting the controller to the first driving member 1321, the output end of the first driving member 1321 is precisely rotated, so as to precisely control the number of rotation turns of the first conveying roller 1322, and further ensure the length accuracy of the electrode sheet conveyed by the first conveying roller 1322.

[0057] Exemplarily, the first linear module 131 may include a servo motor, a lead screw, and a moving member. The output end of the servo motor is connected to the lead screw. The moving member is sleeved on the lead screw and is threadedly connected to the lead screw. The first sliding carriage 120 is connected to the moving member. The first driving member 1321 may be a servo motor, the first detection sensor 141 may be a photoelectric switch, and the controller may be a programmable logic controller.

[0058] Such as Figure 2As shown, in an embodiment of the present application, the pole piece roller feeding and rectifying device 100 further includes a second linear module (not shown in the figure) and a pressure roller 150. The second linear module is disposed on the first sliding frame 120. The pressure roller 150 is rotatably disposed at the output end of the second linear module. The second linear module is configured to drive the pressure roller 150 to approach or move away from the first conveying roller 1322 along the second direction X, where the second direction X is perpendicular to the first direction Y. The second linear module is electrically connected to the controller.

[0059] In this embodiment, by electrically connecting the controller to the second linear module, before the pole piece is conveyed to the first conveying roller 1322, the controller controls the output end of the second linear module to move along the direction away from the second direction X, so as to drive the pressure roller 150 to synchronously move along the direction away from the second direction X to move the pressure roller 150 away from the first conveying roller 1322, thereby facilitating the pole piece to be conveyed into the gap between the first conveying roller 1322 and the pressure roller 150. After the pole piece is conveyed into the gap between the first conveying roller 1322 and the pressure roller 150, the controller controls the output end of the second linear module to move along the second direction X to move the pressure roller 150 closer to the first conveying roller 1322 to clamp the pole piece. Then, the controller controls the first driving member 1321 to drive the first conveying roller 1322 to rotate to accurately convey the pole piece by using the friction force after clamping the pole piece, effectively improving the length accuracy of the conveyed pole piece.

[0060] Exemplarily, the second linear module can be a cylinder or a hydraulic cylinder.

[0061] As Figure 1 and Figure 2 As shown, in an embodiment of the present application, the pole piece roller feeding and rectifying device 100 further includes a third linear module 133 and a guiding member 160. The third linear module 133 is disposed on the first sliding frame 120. One end of the guiding member 160 is rotatably connected to the fixed end of the third linear module 133. The output end of the third linear module 133 is connected to the side of the guiding member 160 away from the pole piece, and is configured to drive the guiding member 160 to rotate around the first direction Y relative to the fixed end of the third linear module 133. The third linear module 133 is electrically connected to the controller.

[0062] In this embodiment, by electrically connecting the controller to the third linear module 133, the output end of the third linear module 133 is controlled to extend or contract along the second direction X, so as to drive the guiding member 160 to rotate around the first direction Y relative to the fixed end of the third linear module 133, so as to facilitate adjusting the included angle between the guiding member 160 and the third linear module 133 according to the feeding requirement, and further ensuring that the pole piece can be accurately conveyed to the winding station of the winding device along the trajectory of the guiding member 160.

[0063] Exemplarily, the third linear module 133 can be a cylinder or a hydraulic cylinder.

[0064] As Figure 1 and Figure 2 shown, in the above embodiments of the present application, the sheet feeding and deviation correcting device 100 further includes an elastic member 170. The output end of the third linear module 133 abuts against the side of the guiding member 160 away from the sheet, and the elastic member 170 is respectively connected to the fixed end of the third linear module 133 and the guiding member 160.

[0065] In this embodiment, by abutting the output end of the third linear module 133 against the side of the guiding member 160 away from the sheet, and connecting the elastic member 170 to the fixed end of the third linear module 133 and the guiding member 160 respectively, when the controller controls the output end of the third linear module 133 to extend along the second direction X, under the abutting action between the output end of the third linear module 133 and the guiding member 160, the guiding member 160 can be driven to rotate around the first direction Y relative to the fixed end of the third linear module 133 and move away from the third linear module 133, so as to increase the included angle between the guiding member 160 and the third linear module 133, and during this process, the elastic member 170 is stretched to generate a restoring elastic force. When the controller controls the output end of the third linear module 133 to contract along the direction away from the second direction X, under the action of the restoring elastic force of the elastic member 170, the guiding member 160 can be driven to automatically rotate around the first direction Y relative to the fixed end of the third linear module 133 and move closer to the third linear module 133, so as to automatically reduce the included angle between the guiding member 160 and the third linear module 133.

[0066] Exemplarily, the elastic member 170 can be a tension spring.

[0067] As Figure 1 and Figure 2 shown, in the above embodiments of the present application, the sheet feeding and deviation correcting device 100 further includes a support 181 and a rolling member 182. The support 181 is connected to the output end of the third linear module 133. The rolling member 182 is rotatably arranged at one end of the support 181 away from the third linear module 133 and abuts against the side of the guiding member 160 away from the sheet.

[0068] In this embodiment, by connecting the support 181 to the output end of the third linear module 133, the rolling member 182 is rotatably arranged at one end of the support 181 away from the third linear module 133 and abuts against the side of the guide member 160 away from the pole piece. In this way, when the controller controls the output end of the third linear module 133 to extend along the second direction X, it can drive the support 181 and the rolling member 182 to move synchronously along the second direction X, so that under the abutting action of the rolling member 182 and the guide member 160, the guide member 160 can be driven to rotate around the first direction Y relative to the fixed end of the third linear module 133 and move away from the third linear module 133 to increase the angle between the guide member 160 and the third linear module 133, and during this process, the elastic member 170 is stretched to generate a reset elastic force. When the controller controls the output end of the third linear module 133 to contract along the direction away from the second direction X, it can drive the support 181 and the rolling member 182 to move synchronously along the direction away from the second direction X, so that under the action of the reset elastic force of the elastic member 170, the guide member 160 can be driven to automatically rotate around the first direction Y relative to the fixed end of the third linear module 133 and move closer to the third linear module 133 to automatically reduce the angle between the guide member 160 and the third linear module 133.

[0069] As Figure 1 shown, in the above embodiment of the present application, the pole piece roller feeding and deviation correcting device 100 further includes a hinge shaft 190, and one end of the guide member 160 is hinged to the fixed end of the third linear module 133 through the hinge shaft 190.

[0070] In this embodiment, one end of the guide member 160 is hinged to the fixed end of the third linear module 133 through the hinge shaft 190, so that the guide member 160 can rotate around the axis of the hinge shaft 190 relative to the fixed end of the third linear module 133, thereby changing the angle between the guide member 160 and the third linear module 133, and further ensuring that the pole piece can be accurately conveyed to the winding station of the winding device according to the trajectory of the guide member 160.

[0071] As Figure 2 shown, in an embodiment of the present application, the pole piece roller feeding and deviation correcting device 100 further includes a coupling 1323, and the output end of the first driving member 1321 is connected to the first conveying roller 1322 through the coupling 1323.

[0072] In this embodiment, the output end of the first driving member 1321 is connected to the first conveying roller 1322 through the coupling 1323, so that the first conveying roller 1322 can accurately and smoothly rotate synchronously with the output end of the first driving member 1321, thereby ensuring the length accuracy of the pole piece conveyed by the first conveying roller 1322.

[0073] As Figure 3As shown, in any of the above embodiments of the present application, the pole piece roller feeding and deviation correcting device 100 further includes a second detection sensor 142. The second detection sensor 142 is disposed on a side of the first frame 110 away from the first conveying roller 1322 and is electrically connected to the controller, and is used to detect whether the pole piece at the feeding end deviates from a preset position along the first direction Y.

[0074] The pole piece roller feeding and deviation correcting device 100 further includes a second frame, a second sliding frame, a fourth linear module, a second conveying roller, and a second driving member (not shown in the figure).

[0075] Among them, the second sliding frame is slidably connected to the second frame. The fourth linear module is disposed on the second frame, and an output end of the fourth linear module is connected to the second sliding frame and is used to drive the second sliding frame to reciprocate linearly relative to the second frame along the first direction Y. The second conveying roller is rotatably disposed on the second sliding frame, and the second driving member is disposed on the second sliding frame. An output end of the second driving member is connected to the second conveying roller. The controller is electrically connected to the second detection sensor 142 and the fourth linear module respectively, and is electrically connected to the second driving member.

[0076] In this embodiment, when the pole piece at the feeding end deviates from the preset position along the first direction Y, the second detection sensor 142 disposed on a side of the frame away from the first conveying roller 1322 feeds back a deviation signal to the controller. The controller controls the output end of the fourth linear module to move along a direction away from the first direction Y according to the deviation signal fed back by the second detection sensor 142, so as to drive the second sliding frame to synchronously slide relative to the second frame along a direction away from the first direction Y, so that the second conveying roller and the second driving member disposed on the second sliding frame synchronously slide relative to the second frame along a direction away from the first direction Y, and further drive the pole piece to move toward a direction away from the first direction Y to return to the preset position, thereby realizing the deviation correcting function of the pole piece at the feeding position and further ensuring the position accuracy of the pole piece. At the same time, by electrically connecting the controller to the second driving member, the output end of the second driving member is accurately rotated, so as to accurately control the number of rotations of the second conveying roller, and further ensure the length accuracy of the pole piece conveyed by the second conveying roller.

[0077] Exemplarily, the fourth linear module may include a servo motor, a lead screw, and a moving member. An output end of the servo motor is connected to the lead screw.
