Description

Technical Field

[0002] In the manufacturing process of lithium-ion batteries, winding is the core process for forming the battery cell. In traditional processes, the electrode sheets are transported to the winding mechanism in a continuous strip form under tension control via a series of rollers.

[0003] Before the cell winding station, the electrode sheets are usually cut by a laser cutting mechanism. When the electrode sheet is cut, its original tension disappears instantly, turning it into a free, tension-free sheet. However, the cut electrode sheet loses its tension support and can no longer be stably and accurately fed into the winding needle or winding station by the traditional roller friction drive method, resulting in winding failure and seriously affecting the production cycle and cell quality.

Detailed Implementation

[0019] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0020] Example 1 Reference Figures 1 to 5 The present invention provides an electrode feeding device in embodiment 1, comprising a drive correction mechanism 100 and a feeding clamping mechanism 200. The drive correction mechanism 100 includes a drive assembly 110 and a correction assembly 120. The drive assembly 110 is used to drive the electrode to move. The drive assembly 110 includes a first support 111, a drive roller 112, a first motor 113 and a pressure roller module 114. The drive roller 112 is rotatably connected to the first support 111. The first motor 113 is used to drive the drive roller 112 to rotate. The pressure roller module 114 is used to press the electrode onto the drive roller 112. The correction assembly 120 is used to drive the pressure roller module 114 to move along the width direction of the electrode.

[0021] Furthermore, the electrode feeding clamping mechanism 200 is used to limit the movement of the electrode to a set route. It is located on one side of the drive correction mechanism 100 and includes a wall plate 210, a first limiting module and a second limiting module disposed on the wall plate 210. The first limiting module and the second limiting module are disposed opposite to each other and work together to constrain the movement path of the electrode.

[0022] Understandably, after the electrode is cut, it enters the drive correction mechanism 100. At this time, the front end of the electrode is located between the pressure roller module 114 and the drive roller 112. The pressure roller module 114 moves to press the front end of the electrode onto the drive roller 112. Then, the first motor 113 drives the drive roller 112 to rotate. The drive roller 112 moves the electrode forward through friction. At the same time, the correction component 120 monitors the position of the electrode in real time. If the electrode deviates, the correction component 120 moves and drives the pressure roller module 114 to move along the width of the electrode to correct the lateral position of the electrode. After correction, the electrode enters the limiting channel between the first limiting module and the second limiting module, so that the electrode moves to the winding station along the set route. Thus, it can provide power and guidance for the tension-free single-segment electrode, ensuring that the electrode can be stably transported to the winding station. At the same time, it can eliminate the lateral deviation or shaking that may occur during the transport of the electrode, ensuring the stability of its movement trajectory.

[0023] In some preferred embodiments, the first limiting module is a first air blowing module 220, and the second limiting module is a support module 230. The support module 230 is located directly below the first air blowing module 220 and is used to support the electrode. The gas blown out by the first air blowing module 220 blows towards the top of the electrode.

[0024] Understandably, the support module 230 can support the electrode sheet, while the airflow blown downward by the first air blowing module 220 forms an air film on the top of the electrode sheet and generates a certain pressure. On the one hand, it can prevent the electrode sheet from shaking, shifting or wrinkling during transportation, thereby improving the alignment of the electrode sheet during winding. On the other hand, the continuously blown downward airflow can blow away dust, debris and other contaminants that may adhere to the electrode sheet during processing, ensuring the cleanliness of the electrode sheet surface and thus improving the quality of the battery cell.

[0025] Furthermore, the first air blowing module 220 includes a first bracket 221, a first air blowing base plate 222 disposed on the first bracket 221, and a first air blowing plate 223 disposed at the bottom of the first air blowing base plate 222. The first bracket 221 is connected to the wall panel 210. The bottom of the first air blowing base plate 222 is provided with a first cavity 2221, and the top of the first air blowing base plate 222 is provided with a first air inlet connector 224. The first air inlet connector 224 communicates with the first cavity 2221 and is connected to an external air source. The first air blowing plate 223 has multiple first air blowing holes 2231, and the first cavity 2221 communicates with the first air blowing holes 2231.

[0026] It is understandable that an external air source enters the first cavity 2221 through the first air inlet connector 224. After being stabilized in the first cavity 2221, the high-pressure gas is blown out evenly downwards from multiple first air blowing holes 2231. The gas blown out from the multiple first air blowing holes 2231 forms a continuous, stable and uniform gas film between the bottom plane of the first air blowing plate 223 and the top surface of the electrode.

[0027] Furthermore, the first bracket 221 is connected to the wall panel 210 by fastening bolts (not shown in the attached drawings). The wall panel 210 is provided with a plurality of first threaded holes, and the first bracket 221 is provided with a plurality of waist-shaped holes 2211. The length direction of the waist-shaped holes 2211 is arranged vertically. A fine adjustment module 225 is provided above the first bracket 221. The fine adjustment module 225 includes an adjustment seat 2251, an upper adjustment bolt 2252, and a lower adjustment bolt 2253. The adjustment seat 2251 is fixed to the wall panel 210. The adjustment seat 2251 has two second threaded holes. The upper adjustment bolt 2252 and the lower adjustment bolt 2253 are threadedly connected to the two second threaded holes respectively.

[0028] Understandably, when it is necessary to adjust the gap between the first air blowing module 220 and the support module 230, the fastening bolts are loosened, and then the upper adjustment bolt 2252 or the lower adjustment bolt 2253 is rotated. The upper adjustment bolt 2252 or the lower adjustment bolt 2253 pushes the first bracket 221 to move up or down, thereby driving the first air blowing module 220 to move up or down as a whole until the gap between the first air blowing module 220 and the support module 230 is adjusted to the set gap. Finally, the fastening bolts are tightened to firmly lock the entire first air blowing module 220 in the set position. Thus, it can adapt to electrode sheets of different thicknesses and improve the flexibility of the equipment.

[0029] In some preferred embodiments, the support module 230 includes a second bracket 231 and an electrode support plate 232 disposed on the second bracket 231. The second bracket 231 is disposed on the wall panel 210. The electrode support plate 232 is parallel to the first air blowing plate 223. The upper surface of the electrode support plate 232 is smooth. The structure of the second bracket 231 is the same as that of the first bracket 221. The second bracket 231 and the first bracket 221 are arranged symmetrically in the upper and lower parts.

[0030] Understandably, the electrode, pushed by the drive correction mechanism 100, enters the slit formed by the upper first air blowing plate 223 and the lower electrode support plate 232. The gas blown out by the first air blowing plate 223 forms an air film, so that the first air blowing plate 223 and the top of the electrode are not in contact. The air film provides upward buoyancy to reduce the positive pressure, while ensuring that the electrode does not drift upward. The bottom of the electrode makes slight contact with the smooth upper surface of the electrode support plate 232, while the lower electrode support plate 232 provides a solid physical reference surface, supporting the weight of the electrode and limiting its fall, thereby ensuring the stability of the electrode's running trajectory.

[0031] In some preferred embodiments, the correction assembly 120 includes a second support 121, a second motor 122, a lead screw 123, a lead screw nut 124, and a translation seat 125. The second motor 122 is mounted on the second support 121. The lead screw 123 is rotatably connected to the second support 121 via two bearing seats 126. One end of the lead screw 123 is connected to the output shaft of the second motor 122. The lead screw nut 124 is threadedly connected to the lead screw 123. The translation seat 125 is fixedly connected to the lead screw nut 124. The pressure roller module 114 is mounted on the translation seat 125. The first support 111 is mounted on the second support 121. The axial direction of the lead screw 123 is the width direction of the electrode sheet.

[0032] Understandably, when the electrode sheet shifts laterally, the second motor 122 drives the lead screw 123 to rotate. The lead screw 123 drives the lead screw nut 124 to move along the axial direction of the lead screw 123. The lead screw nut 124 drives the translation seat 125 and the entire pressure roller module 114 to move along the width direction of the electrode sheet. Thus, the moving distance and speed of the translation seat 125 and the pressure roller module 114 can be precisely controlled to ensure the accuracy and stability of the correction action.

[0033] In some preferred embodiments, the pressure roller module 114 includes a vertical plate 1141, a cylinder 1142, a lifting seat 1143, and a pressure roller 1144. The vertical plate 1141 is mounted on the translation seat 125, the cylinder 1142 is mounted on the vertical plate 1141, the lifting seat 1143 is mounted on the extension end of the cylinder 1142, and both ends of the pressure roller 1144 are rotatably connected to the lifting seat 1143. The pressure roller 1144 is parallel to the drive roller 112 and is located directly below the drive roller 112.

[0034] Understandably, after the electrode is cut, the cylinder 1142 drives the lifting seat 1143 to rise. The lifting seat 1143 drives the pressure roller 1144 to approach the drive roller 112, and the electrode is clamped between the pressure roller 1144 and the drive roller 112. Then, the first motor 113 drives the drive roller 112 to rotate. The drive roller 112 drives the electrode to move forward through friction. At this time, the pressure roller 1144 rotates in the opposite direction under the action of friction, thereby realizing the smooth conveying of the electrode and avoiding the electrode slipping.

[0035] Furthermore, a U-shaped frame 127 is provided on the second support 121, and two oppositely arranged correction sensors 128 are provided on the U-shaped frame 127. The electrode passes through the opening of the U-shaped frame 127, and the two correction sensors 128 are used to sense the edge position of the electrode.

[0036] Understandably, during electrode transport, the electrode passes through the opening of the U-shaped frame 127. One of the correction sensors 128 acts as a transmitter, and the other as a receiver. The transmitter is perpendicular to the electrode and emits a beam of detection light. The receiver is directly opposite the transmitter and receives the detection light. The electrode passes horizontally through the detection light. At this time, the electrode blocks part of the vertical photoelectric light, while the part of the light that is not blocked by the electrode is received by the receiver. The receiver detects the edge position of the electrode by the area of ​​the received light, thereby accurately detecting the lateral offset of the electrode, which facilitates the correction component 120 to accurately correct the lateral offset of the electrode.

[0037] Furthermore, two support plates 115 are provided on both sides of the first support 111, and the two support plates 115 are used to support the electrode sheet.

[0038] Understandably, before the electrode enters the drive correction mechanism 100, the support plate 115 on the inlet side can support the electrode, ensuring that the electrode enters the pressing area of ​​the drive roller 112 and the pressure roller 1144 in a horizontal and flat posture. This avoids the risk of impact, jamming, or edge curling caused by the electrode tip sagging. After the electrode is conveyed out from between the drive roller 112 and the pressure roller 1144, the support plate 115 on the outlet side can immediately receive the electrode and then enter the electrode feeding clamping mechanism 200. This prevents the electrode tip from sagging or uncontrolled shaking due to its own weight and inertia, ensuring smooth electrode conveying.

[0039] Example 2 Reference Figure 6 and Figure 7 The difference between Embodiment 2 and Embodiment 1 lies in the structure of the support module 230. Specifically, the support module 230 includes a third bracket 233, a second air-blowing base plate 234 disposed on the third bracket 233, and a second air-blowing plate 235 disposed on the top of the second air-blowing base plate 234. The third bracket 233 is disposed on the wall panel 210. A second cavity 2341 is disposed on the top of the second air-blowing base plate 234, and a second air inlet connector 236 is disposed on the bottom of the second air-blowing base plate 234. The second air inlet connector 236 is connected to the second cavity 2341 and is connected to an external air source. The second air-blowing plate 235 has multiple second air-blowing holes 2351. The second cavity 2341 is connected to the second air-blowing holes 2351. The second air-blowing plate 235 is parallel to the first air-blowing plate 223. The structure of the third bracket 233 is the same as that of the first bracket 221. The third bracket 233 and the first bracket 221 are arranged symmetrically above and below each other.

[0040] Understandably, an external air source enters the second cavity 2341 through the second air inlet connector 236. After being pressurized within the second cavity 2341, the high-pressure gas is uniformly blown upwards from multiple second air outlets 2351. The gas blown out from these outlets forms a continuous, stable, and uniform gas film between the top plane of the second air outlet plate 235 and the bottom surface of the electrode. Simultaneously, the first air outlet module 220 operates, blowing gas downwards to form a continuous, stable, and uniform gas film between the bottom plane of the first air outlet plate 223 and the top surface of the electrode. Therefore, the upper surface of the electrode has no physical contact with the first air outlet plate 223, and the lower surface of the electrode has no physical contact with the second air outlet plate 235. By precisely controlling the pressure of the two gas films, the electrode is completely suspended between them. This avoids surface damage caused by contact transport and reduces friction during transport, ensuring smooth delivery.
