Description

Technical Field

[0001] This utility model relates to the field of battery coating technology, and in particular to a winding and pressing roller mechanism for a battery electrode coating machine. Background Technology

[0002] During battery production, coating materials are bonded to foils through a coating process, followed by drying in an oven, and then the electrode sheets are rolled into coils of a certain diameter. After winding, the electrode sheets need to be neat and easy to transport, and the winding tension must be consistent. However, in current coating processes, the tension of the electrode sheets changes after baking, affecting the flatness and tension of the rolled electrode sheets. This causes the electrode sheets to slip and deviate, resulting in damage to the electrode sheets and tabs, increasing the scrap rate of the electrode sheets, and also affecting the welding effect in subsequent battery processes. Utility Model Content

[0003] The purpose of this invention is to provide a winding and pressing roller mechanism for a battery electrode coating machine to solve the problems encountered in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A winding and pressing roller mechanism for a battery electrode coating machine includes a support frame, a cylinder mounting assembly, a pressing roller support assembly, and a pressing roller. The lower part of the support frame is fixedly connected to the cylinder mounting assembly via an auxiliary crossbeam, and the upper part of the support frame is fixedly connected to the pressing roller support assembly via a main crossbeam. The working end of the pressing roller support assembly is rotatably connected to the pressing roller via a support plate, and the working end of the cylinder mounting assembly is drive-connected to the support plate.

[0005] In the above scheme, two sets of cylinder mounting assemblies are provided on the auxiliary crossbeam, and two sets of pressure roller support assemblies are provided on the main crossbeam. The two sets of pressure roller support assemblies are connected by a crossbar. A set of cylinder mounting assemblies is also provided on the upper part of the pressure roller support assembly. The upper and lower parts of the pressure roller support assembly are rotatably connected to the pressure roller through support plates.

[0006] In the above scheme, the cylinder mounting assembly includes a cylinder base and a cylinder. The cylinder base is fixed to one side of the auxiliary crossbeam and faces the mounting direction of the pressure roller. The top side of the cylinder base is rotatably connected to the cylinder via a hinge seat, and the top working end of the cylinder is drively connected to the support plate via a floating joint. A connecting piece is fixed downward in the middle of the support plate, and the connecting piece is rotatably connected to the floating joint.

[0007] In the above scheme, the pressure roller support assembly includes a pressure roller base and a bearing seat. The lower part of the pressure roller base has a circular hole. The bearing seat is installed on the inner side of the pressure roller base. A first bearing is installed in the bearing seat. The outer ring of the first bearing is connected to the support plate through a bushing ring. The inner ring of the first bearing is connected to the crossbar through a locking ring.

[0008] In the above scheme, the pressure roller has a long cylindrical structure, and second bearings are installed inside both ends of the pressure roller. A central rod is fixed in the inner ring of the second bearing by a snap ring, and the end of the support plate is connected to the central rod.

[0009] Compared with existing technologies, the beneficial effects of this utility model are as follows: During operation, the drive cylinder of the cylinder mounting assembly extends, and the support plate drives the first bearing of the pressure roller support assembly to rotate. Simultaneously, the support plate drives the pressure roller to extend and press against the electrode sheet, maintaining the flatness and tension of the wound electrode sheet. This solution adds an electrode sheet pressure roller mechanism to the original winding point. Using this pressure roller mechanism, under the pressure of the electrode sheet, avoids the release of tension in the large roll of electrode sheet after cutting, which could cause electrode sheet slippage, misalignment, damage, and scrap. This ensures the consistency of the wound electrode sheet, improves product quality, and provides a good condition for subsequent battery welding processes. Attached Figure Description

Detailed Implementation

[0012] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the utility model will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model, and therefore only show the relevant components of this utility model.

[0013] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] Example 1, as Figure 1 and Figure 2 As shown, a battery electrode coating machine winding and pressing roller mechanism includes a support frame 1, a cylinder mounting assembly 2, a pressing roller support assembly 3, and a pressing roller 4. The support frame 1 is installed at the electrode winding point in the battery coating process. These components cooperate with each other to form a pressing roller mechanism for winding the electrode.

[0016] The lower part of the support frame 1 is fixedly connected to the cylinder mounting assembly 2 via an auxiliary crossbeam 11, which primarily supports the cylinder mounting assembly 2. The upper part of the support frame 1 is fixedly connected to the pressure roller support assembly 3 via a main crossbeam 12, which also provides stable support for the pressure roller support assembly 3. The working end of the pressure roller support assembly 3 is rotatably connected to the pressure roller 4 via a support plate 31. One end of the support plate 31 is rotatably connected to the working end of the pressure roller support assembly 3, and the other end of the support plate 31 is rotatably connected to the pressure roller 4. Furthermore, in order to drive the support plate 31 to smoothly press down the electrode sheet, the working end of the cylinder mounting assembly 2 is connected to the support plate 31 via a transmission connection.

[0017] In operation, the drive cylinder of cylinder mounting assembly 2 extends, and the support plate 31 drives the first bearing 34 of the pressure roller support assembly 3 to rotate. At the same time, the support plate 31 drives the pressure roller 4 to extend and press the electrode sheet, maintaining the flatness and tension of the wound electrode sheet. This solution adds an electrode sheet pressure roller mechanism to the original winding point. Using the pressure roller mechanism on the electrode sheet, the tension of the large roll of electrode sheet after cutting is prevented from being released outwards, causing electrode sheet slippage, misalignment, damage, and scrap. This ensures the consistency of the wound electrode sheet and improves product quality.

[0018] During implementation, two sets of cylinder mounting components 2 are provided on the auxiliary crossbeam 11, and two sets of pressure roller support components 3 are provided on the main crossbeam 12. The two sets of pressure roller support components 3 are connected by crossbar 32. Through the two sets of pressure roller support components 3 and the two sets of cylinder mounting components 2, stable support is provided for the pressure roller 4, thereby better pressing the electrode sheet and keeping it flat and under tension.

[0019] Example 2 differs from Example 1 in that a set of cylinder mounting components 2 is also provided on the upper part of the pressure roller support assembly 3. Figure 1 and Figure 2 (Not shown in the diagram, only the extra crossbar 32 at the top is shown). The upper and lower parts of the pressure roller support assembly 3 are rotatably connected to the pressure roller 4 via support plates 31. Figure 1 A pressure roller 4 is provided at the lower part of the main crossbeam 12, which facilitates the flattening of the electrode sheet passing through the gap between the two support plates 31 from bottom to top, and also serves as a guide. By providing a pressure roller 4 at the upper part of the main crossbeam 12, it is convenient to flatten the electrode sheet passing through the gap between the two support plates 31 from top to bottom, and also serves as a guide.

[0020] Example 3, please refer to Figure 1 Based on Embodiment 1, the support frame 1 includes a lower support 13 and an upper support 14. The top of the lower support 13 is connected to the upper support 14. The area of ​​the upper support 14 is larger than the area of ​​the lower support 13 because the cross-sectional area of ​​the main crossbeam 12 is also larger than the cross-sectional area of ​​the auxiliary crossbeam 11, thus ensuring stable installation. The auxiliary crossbeam 11 is installed between the two lower supports 13, and the main crossbeam 12 is installed between the two upper supports 14.

[0021] Example 4, please refer to Figure 3 and Figure 4Based on Embodiment 1, the cylinder mounting assembly 2 includes a cylinder base and a cylinder. The cylinder base is fixed to one side of the auxiliary crossbeam 11 and faces the mounting direction of the pressure roller 4, facilitating the raising and lowering of the top support plate 31 to adjust the position of the flattened electrode sheet. As a preferred embodiment, the top side of the cylinder base is rotatably connected to the cylinder via a hinge seat 23, and the top working end of the cylinder is drive-connected to the support plate 31 via a floating joint 24, allowing adjustment of certain raising and lowering deviations. Additionally, a connecting piece 35 is fixed downwards in the middle of the support plate 31, and the connecting piece 35 is rotatably connected to the floating joint 24. The floating joint 24 is used to adjust the tension, avoiding cylinder driving errors and ensuring the pressure and level of the pressure roller 4.

[0022] The cylinder base includes a first base 21 and a second base 22. Semi-circular slots are respectively formed on the inner sides of the first base 21 and the second base 22. The first base 21 engages with one side of the outer wall of the auxiliary crossbeam 11, and the second base 22 engages with the other side of the outer wall of the auxiliary crossbeam 11. The first base 21 and the second base 22 are fixedly connected by screws. As a preferred embodiment, the top side of the second base 22 is fixedly connected to the hinge seat 23, which positions the cylinder during installation and facilitates pressing down on or under the top support plate 31. Furthermore, the slotted connection between the first base 21 and the second base 22 improves the horizontal installation accuracy.

[0023] Example 5, please refer to Figure 3 and Figure 5 Based on Embodiment 1, the pressure roller support assembly 3 includes a pressure roller base and a bearing seat 36. A circular hole 33 is provided at the lower part of the pressure roller base. The bearing seat 36 is installed on the inner side of the pressure roller base. A first bearing 34 is installed in the bearing seat 36. The outer side of the first bearing 34 is located in the circular hole 33. The outer ring of the first bearing 34 is connected to the support plate 31 through a bushing ring 37. The bushing ring 37 is used to lock the mounting hole of the support plate 31. The inner ring of the first bearing 34 is connected to the crossbar 32 through a locking ring. The locking ring is used to press the crossbar 32.

[0024] The pressure roller base includes a third base 38 and a fourth base 39. Semi-circular slots are formed on the inner sides of both the third base 38 and the fourth base 39. The third base 38 engages with one side of the outer wall of the main crossbeam 12, and the fourth base 39 engages with the other side of the outer wall of the main crossbeam 12. The third base 38 and the fourth base 39 are fixedly connected by screws. The bottom inner side of the third base 38 is fixedly connected to the bearing seat 36; therefore, the bottom area of ​​the third base 38 is larger than that of the fourth base 39 to accommodate the bearing seat 36. Furthermore, the slotted connection between the third base 38 and the fourth base 39 improves the horizontal installation accuracy.

[0025] Example 6, please refer to Figure 3 and Figure 6The pressure roller 4 has a long cylindrical structure. Second bearings 41 are installed inside both ends of the pressure roller 4. A central rod 42 is fixed to the inner ring of the second bearing 41 by a snap ring. The end of the support plate 31 is connected to the central rod 42. Due to the rotational property of the second bearings 41, the support plate 31 and the pressure roller 4 are rotatably connected. The pressure roller 4 adheres to the electrode sheet, ensuring no damage to the electrode sheet. Because it flattens and guides the electrode sheet, the electrode sheet has a certain bending angle, which also reduces the risk of metal introduction during friction.
