DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Generally, the mechanisms of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0028] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0029] As disclosed in the background technology, during the winding process of the winding machine in the prior art, the material strip may deviate due to errors in the incoming material, such as uneven material strip thickness, wavy edges of the material strip, serpentine bends of the material strip, etc. The deviation of the material strip leads to poor alignment of the battery cells, thereby creating a safety hazard for the battery cells.

[0030] Furthermore, there are also correction mechanisms that can correct the web. However, these correction mechanisms usually achieve this by directly adjusting the angle of the web roller, which cannot adapt to the position of the web roller in real time. Furthermore, their adaptability is poor, and they are not very adaptable to webs of different sizes. Furthermore, during the correction process, the web conveying angle changes, making it easy for tabs to fold or flanging, which also affects conveying safety and web quality.

[0031] In order to solve the above problems, the present invention provides a novel strip correction mechanism and a winding machine. It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0032] First embodiment

[0033] See also Figures 1 to 4 This embodiment provides a strip correction device 100 that effectively inspects and corrects the strip, ensuring proper alignment during the cell winding process. This significantly improves the quality of the produced cells and increases the product yield. The device is also highly adaptable, suitable for use with strips of varying specifications. It effectively prevents tab folding and bending, significantly improving the cell winding yield and the equipment's changeover efficiency.

[0034] The material strip correction device 100 provided in this embodiment includes a material strip detection mechanism 110 and a material strip correction mechanism 130. The material strip correction mechanism 130 includes a correction drive assembly 150, a correction mounting frame 170 and a correction roller group 190. The correction roller group 190 is rotatably mounted on the correction mounting frame 170 and is used to carry the material strip. The correction drive assembly 150 is arranged on the bottom side of the correction mounting frame 170 and is transmission-connected to the correction mounting frame 170. The material strip detection mechanism 110 is arranged on one side of the correction roller group 190 and is communication-connected to the correction drive assembly 150 for detecting the position of the material strip and generating position information. The correction drive assembly 150 is used to drive the correction mounting frame 170 to rotate according to the position information so that the correction roller group 190 corrects the position of the material strip.

[0035] It should be noted that the strip correction device 100 provided in this embodiment is suitable for use in a winding machine and is capable of correcting the position of the strip during the winding process. The strip can be a pole piece 200 or a diaphragm. The correction roller assembly 190 is positioned at the strip conveyor position and is capable of winding and carrying the strip. During the strip transport process, the correction roller assembly 190 oscillates to achieve correction of the strip.

[0036] In this embodiment, the strip detection mechanism 110 detects the real-time position of the strip and generates position information. When the strip deviates, the correction drive assembly 150 drives the correction mounting frame 170 to rotate based on this position information, thereby causing the correction roller assembly 190 to deflect and correct the position of the strip. The strip correction device 100 provided herein can effectively detect and correct the strip, ensuring the alignment of the strip during the battery cell winding process, greatly improving the quality of the produced battery cells and increasing the product qualification rate.

[0037] Correction roller assembly 190 includes a first correction roller 191 and a second correction roller 193. These rollers are arranged parallel to each other and are located on either side of a correction mounting frame 170. Correction mounting frame 170 is used to simultaneously drive the first and second correction rollers 191, 193 to oscillate, thereby correcting the web. Specifically, the first and second correction rollers 191, 193 are of identical size. The web is simultaneously wound around and carried on both correction rollers 191, 193, and can be moved from the first correction roller 191 to the second correction roller 193.

[0038] The correction mounting frame 170 includes a base plate 171 and support plates 173 disposed on either side of the base plate 171. The first correction roller 191 has its ends rotatably connected to one end of the support plates 173, while the second correction roller 193 has its ends rotatably connected to the other end of the support plates 173. Both the first correction roller 191 and the second correction roller 193 are spaced apart from the base plate 171, which is connected to the correction drive assembly 150. Specifically, the two support plates 173 are disposed on either side of the base plate 171 and are integrally formed with the base plate 171. Each support plate 173 has bearings at both ends, which connect to the first correction roller 191 or the second correction roller 193 via the bearings, thereby achieving a rotational connection between the first correction roller 191 and the second correction roller 193.

[0039] In this embodiment, the ends of the correction roller assembly 190 are further provided with tab guides 195. The tab guides 195 are connected to the correction mounting frame 170, and both sides of the tab guides 195 are folded outward to guide the tabs at the edges of the material strip. Specifically, the ends of the first correction roller 191 and the second correction roller 193 are each provided with tab guides 195. The tab guides 195 include a main body and a guide portion. The main body is arc-shaped and matches the shape of the first correction roller 191 and the second correction roller 193. The main body is fixed to the end of the support plate 173 by screws and is spaced apart from the first correction roller 191 and the second correction roller 193 to avoid affecting the normal conveyance of the material strip. The guide portions are provided on both sides of the main body and are both arc-shaped and folded outward, allowing the tabs to enter the main body along the guide portions during feeding, thereby preventing the tabs from folding or buckling when the material strip enters the first correction roller 191 or the second correction roller 193.

[0040] The strip detection mechanism 110 includes a detection sensor 111 and a detection drive module 113. The detection sensor 111 is arranged corresponding to the correction roller set 190 and is in communication with the correction drive assembly 150. The detection drive module 113 is in transmission connection with the detection sensor 111 and is used to drive the detection sensor 111 to perform linear motion relative to the correction roller set 190. Specifically, the detection sensor 111 can be arranged on the side of the second correction roller 193 away from the first correction roller 191. The detection sensor 111 can be a distance sensor that can detect the position of the strip in real time. At the same time, the detection drive module 113 can drive the detection sensor 111 to perform linear motion in a direction parallel to the axis of the second correction roller 193, thereby enabling detection of strips of different widths and specifications.

[0041] The detection drive module 113 includes a detection drive member 115, a drive rail 117 and a slider 119, the drive rail 117 is arranged in parallel on one side of the correction roller group 190, the detection drive member 115 is arranged at one end of the drive rail 117, the slider 119 is slidably arranged on the drive rail 117, and is connected to the detection drive member 115 by transmission, and the detection sensor 111 is arranged on the slider 119, and the slider 119 is used to slide along the drive rail 117 under the drive of the detection drive member 115 to drive the detection sensor 111 to do linear motion. Specifically, the detection drive member 115 can be a stepper motor, and the stepper motor can adjust the rotation direction by a threaded rod cooperating with the thread on the slider 119, so that the rotation is converted into linear motion, and the movement of the slider 119 along the drive rail 117 is realized. Of course, the driving mode between the detection drive member 115 and the slider 119 can also be other types, such as directly driven by a cylinder, which is not specifically limited here.

[0042] The correction drive assembly 150 includes a carrier 151, a driver 152, and a transmission module 153. The carrier 151 is disposed on the bottom side of the correction mounting frame 170. The driver 152 and the transmission module 153 are both disposed on the carrier 151. The driver 152 has an output shaft that is in driving connection with the transmission module 153. The transmission module 153 is connected to the correction mounting frame 170. The driver 152 drives the correction mounting frame 170 to rotate via the transmission module 153. Specifically, the driver 152 can be a motor, which transmits power through the transmission module 153, thereby driving the carrier 151 to rotate, thereby achieving deflection of the first correction roller 191 and the second correction roller 193.

[0043] The transmission module 153 includes a first fixed bracket 154, a second fixed bracket 155, a guide slide 156, a rotating block 157, a first guide column 158, a second guide column (not numbered in the figure), a first rotating sliding block 159 and a second rotating sliding block (not numbered in the figure). The guide slide 156 is movably provided at one end of the first fixed bracket 154 and one end of the second fixed bracket 155 and is connected to the output shaft. The output shaft is used to drive the guide slide 156 to move axially. The rotating block 157 is sleeved on the guide slide 156 and It can rotate relative to the guide slide rod 156, the first guide column 158 is connected to the other end of the first fixed bracket 154, the first rotating sliding block 159 is slidably mounted on the first guide column 158, and can rotate relative to the first guide column 158, the second guide column is connected to the other end of the second fixed bracket 155, the second rotating sliding block is slidably mounted on the second guide column, and can rotate relative to the second guide column, the rotating block 157, the first rotating sliding block 159 and the second rotating sliding block are all connected to the correction mounting frame 170 to drive the correction mounting frame 170 to deflect.

[0044] It should be noted that in the jaw type, in this embodiment, the first guide post 158 ​​and the second guide post are symmetrically arranged, and the first rotating sliding block 159 and the second rotating sliding block have the same shape and specifications.

[0045] In this embodiment, both the first guide post 158 ​​and the second guide post are arranged at an angle, with one end of the first guide post 158 ​​connected to the first fixed bracket 154 and the other end fixed to a top corner edge of the carrier 151. One end of the second guide post is connected to the second fixed bracket 155 and the other end fixed to another top corner edge of the carrier 151. The first guide post 158, the second guide post, the first fixed bracket 154, and the second fixed bracket 155 are all relatively fixed, while the rotating block 157, the first rotating and sliding block 159, and the second rotating and sliding block are all connected to the bottom plate 171, thereby achieving a movable connection with the bottom plate 171.

[0046] It should be noted that in this embodiment, the rotating block 157 is a rotating bearing, which is fixedly mounted on the guide slide 156 and can rotate relative to the guide slide 156. At the same time, the first rotating sliding block 159 and the second rotating sliding block are also rotating bearings and can rotate and slide relative to the first guide column 158 and the second guide column.

[0047] In this embodiment, the rotating block 157, the first rotating sliding block 159, and the second rotating sliding block are all provided with connecting bolts, which are passed through the correction mounting frame 170 to securely connect the rotating block 157, the first rotating sliding block 159, and the second rotating sliding block to the correction mounting frame 170. The connecting bolts enable secure connection of the correction mounting frame 170 to better achieve power transmission.

[0048] In this embodiment, the output shaft is connected to a screw 1521, which is used to rotate under the drive of the output shaft. The screw 1521 is equipped with a threaded transmission block 1523, which is used to perform linear motion under the drive of the screw 1521. The threaded transmission block 1523 is connected to the guide slide 156 and is used to drive the guide slide 156 to perform linear motion. Specifically, the threaded transmission block 1523 is provided with a screw hole, and the thread cooperates with the screw 1521 through the thread, so that when the screw 1521 rotates, it can drive the threaded transmission block 1523 to perform linear motion, and the transmission is more stable. In addition, here, the deceleration effect can be achieved by adjusting the number of turns and pitch of the thread on the screw 1521, so that the threaded transmission block 1523 can perform linear motion more precisely, ensuring the accuracy of the adjustment.

[0049] It should be noted that during actual correction, the motor's output shaft rotates, thereby driving the screw 1521 to rotate. Driven by the threads on the screw 1521, the threaded transmission block 1523 moves along the axis of the screw 1521, thereby driving the guide slide 156 to perform linear motion in the same direction. The guide slide 156 drives the rotating body to rotate, driving the correction mounting frame 170 to rotate. At this time, the first sliding block 159 and the second sliding block adaptively rotate and slide relative to the first guide post 158 ​​and the second guide post, thereby achieving rotation of the entire correction mounting frame 170 and driving the first correction roller 191 and the second correction roller to yaw, thereby achieving the correction of the material strip. The number of revolutions of the motor's output shaft can be determined based on the detection data of the position sensor to achieve real-time adjustment. In addition, the use of multiple rotating bearings to achieve power transmission makes the rotation of the correction mounting frame 170 more stable and controllable. The rotation angle limit of the rotating bearing itself prevents the correction mounting frame 170 from excessive rotation, avoiding damage to the material strip conveyor line.

[0050] In summary, this embodiment provides a strip correction device 100 that uses a strip detection mechanism 110 to detect the real-time position of the strip and generate position information. When the strip deviates, the correction drive assembly 150 can drive the correction mounting frame 170 to rotate based on this position information, thereby causing the correction roller assembly 190 to deflect and correct the position of the strip. Compared to the prior art, the strip correction device 100 provided in this embodiment of the present invention can effectively detect and correct the strip, ensuring the alignment of the strip during the battery cell winding process, greatly improving the quality of the produced battery cells and increasing the product qualification rate.
