Abstract
Description
Technical Field
[0001] This application relates to the field of lithium battery production technology, and in particular to an auxiliary strapping device. Background Technology
[0002] In lithium battery manufacturing, electrodes are typically transported and processed as continuous strip materials. From coating and baking to rolling and slitting, the electrodes must sequentially pass through various processing units of equipment along a pre-defined path, such as ovens, cooling sections, and tensioning mechanisms. To ensure stable operation, the electrodes must be accurately wound around the surfaces of multiple sets of transfer rollers inside the equipment, such as guide rollers, tension rollers, and alignment rollers, thus forming a continuous transport path. Before the equipment officially begins operation, the electrodes need to be threaded along the transport path.
[0003] In related technologies, electrode threading operations mainly rely on manual operation. For example, after the coating process is completed, when the electrode is led out of the oven outlet, the operator needs to manually pull the head of the electrode and thread it one by one along the complex roller layout inside the equipment until the electrode completely covers the entire transmission path.
[0004] However, manual threading is inconvenient due to the limited space inside the equipment, and the threading process requires long periods of bending over and leaning to pull the electrode, resulting in high labor intensity for personnel. Utility Model Content

[0012] Furthermore, the transfer roller also includes a rubber roller, which is disposed opposite to the second steel roller, and the rubber roller and the second steel roller are used to clamp the electrode sheet.

[0025] In related technologies, electrode threading operations mainly rely on manual operation. For example, after the coating process is completed, when the electrode is led out of the oven outlet, the operator needs to manually pull the head of the electrode and thread it one by one along the complex roller layout inside the equipment until the electrode completely covers the entire transmission path.
[0026] However, manual threading is inconvenient due to the limited space inside the equipment, and the threading process requires long periods of bending over and leaning to pull the electrode, resulting in high labor intensity for personnel.
[0027] To address the aforementioned issues, this application provides an auxiliary threading device that can automatically complete the threading of electrode sheets, reducing the labor intensity of personnel.
[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0029] like Figures 1 to 4 As shown in the figure, this application provides an auxiliary belt threading device, including a frame 1, a transmission roller, a drive component 2, a transmission component 3, and a guide rod 4.
[0030] The frame 1 provides a stable support foundation for the entire auxiliary tape-threading device. The transfer rollers are arranged along the transfer path of the electrode 5 and are rotatably mounted on the frame 1. The transfer rollers include various types such as steel rollers, swing rollers 20, and guide rollers 50, and each transfer roller is rotatably mounted on the frame 1 along the transfer path of the electrode 5.
[0031] The drive component 2 is positioned relative to the transmission roller and is rotatably mounted on the frame 1. The transmission component 3 is drivenly connected to the drive component 2, and the drive component 2 can drive the transmission component 3 to move along a closed-loop path to form a continuous transmission circuit.
[0032] The guide rod 4 is mounted on the transmission component 3. The guide rod 4 is used to connect with the electrode 5. For example, the electrode 5 is glued to the guide rod 4 by adhesive bonding. When the guide rod 4 moves with the transmission component 3, it can wind the electrode 5 along the transmission path of the electrode 5 onto the transmission roller to realize the automatic threading function.
[0033] During the threading process, the operator only needs to fix the head of the electrode 5 onto the guide rod 4, activate the drive component 2 to drive the transmission component 3 to move, the transmission component 3 drives the guide rod 4 to move, and the guide rod 4 drives the electrode 5 to pass through each transmission roller in sequence to complete the entire threading operation. This automated threading method greatly reduces the labor intensity of the operator and improves the efficiency and accuracy of threading.
[0034] Specifically, such as Figure 1 As shown in the figure, the electrode 5 enters the auxiliary threading device from the upper left to the right of the frame 1, and after the threading is completed, the electrode 5 moves out from the lower right to the right of the frame 1. In some embodiments, such as Figures 1 to 4 As shown, the transmission component 3 is a chain, and the driving component 2 includes a sprocket 21 and a force-applying component 22. The chain is connected to the sprocket 21, and the force-applying component 22 is connected to the sprocket 21. The force-applying component 22 can drive the sprocket 21 to rotate.
[0035] Specifically, there are multiple sprockets 21, and all of the multiple sprockets 21 are rotatably mounted on the frame 1. The force-applying component 22 can be connected to one of the sprockets 21 and drive the sprocket 21 to rotate, thereby driving the chain to move along the closed-loop path and realizing the precise movement of the guide rod 4.
[0036] In some other embodiments, a synchronous belt and synchronous pulley drive method can be used instead of the chain and sprocket drive method described above. When the synchronous belt moves along the closed-loop path, it drives the guide rod 4 to move.
[0037] Optionally, the force-applying component 22 can be a motor or a rocker arm. For example... Figure 4 As shown in the illustrated embodiment, the force-applying component 22 is a rocker arm, which the operator can rock to drive the sprocket 21 to rotate.
[0038] In some embodiments, chains are provided at both ends of the transfer roller, with the two chains spaced apart, and the guide rod 4 is connected between the two chains. Specifically, sprockets 21 are provided on both sides of the frame 1 to drive the two chains to move synchronously, thereby smoothly moving the guide rod 4, during which the electrode 5 is located between the two chains.
[0039] In some embodiments, such as Figures 1 to 4 As shown, the driving component 2 also includes a driving shaft 23 connected to the force-applying component 22, and the driving shaft 23 is connected to two correspondingly arranged sprockets 21. Specifically, the two coaxially arranged corresponding sprockets 21 are fixedly sleeved on the driving shaft 23. The force-applying component 22 is connected to one end of the driving shaft 23 and is used to drive the driving shaft 23 to rotate. When the driving shaft 23 rotates, it drives the two sprockets 21 on it to rotate synchronously, thereby driving the two chains to move synchronously.
[0040] In some embodiments, such as Figure 1As shown, the transfer rollers include a first steel roller 6 and a second steel roller 7. The first steel roller 6 and the second steel roller 7 are arranged sequentially along the transfer path of the electrode 5, that is, the electrode 5 first passes through the first steel roller 6 and then through the second steel roller 7. Cooling liquid is provided inside both the first steel roller 6 and the second steel roller 7. Specifically, the electrode 5 is at a high temperature after coming out of the oven, and the first steel roller 6 and the second steel roller 7 can cool down the electrode 5 as it passes through.
[0041] In some embodiments, such as Figure 1 As shown, the transfer roller also includes a rubber roller 8, which is arranged opposite to the second steel roller 8. The rubber roller 8 and the second steel roller 8 are used to clamp the electrode sheet 5. When the electrode sheet 5 is transferred, it passes through the gap between the rubber roller 8 and the second steel roller 8 and is subjected to the clamping force of the rubber roller 8 and the second steel roller 8. This allows the tension of the electrode sheet 5 before and after passing through the rubber roller 8 to be separated by the clamping of the rubber roller 8 and the second steel roller 8, which facilitates the segmented adjustment of the tension or position of the electrode sheet 5, so that the electrode sheets 5 before and after passing through the rubber roller 8 do not affect each other.
[0042] Optionally, the rubber roller 8 is fitted with a rubber sleeve, or the rubber roller 8 is an integral structure made of rubber material, and the flexibility of the surface of the rubber roller 8 can prevent damage to the electrode sheet 5.
[0043] When the design of using a rubber sleeve on the rubber roller 8 is adopted, the spindle of the rubber roller 8 can be made of steel, with a replaceable rubber sleeve fitted on the outside. The rubber sleeve is molded from a special rubber material, and its inner surface has a keyway or spline for reliable connection with the spindle. The advantage of this sleeve structure is that maintenance is convenient. When the rubber sleeve is worn or aged, the rubber sleeve can be replaced separately without replacing the entire rubber roller 8.
[0044] When the design of the rubber roller 8 is adopted as an integral structure made of rubber material, the entire rubber roller 8 is made of rubber material and is formed in one step by molding or injection molding process. The two ends of the rubber roller 8 can be embedded with metal bearing seats for mounting bearings and connecting shafts.
[0045] In some embodiments, such as Figure 1 As shown, the frame 1 is also equipped with a web guiding assembly 9. The web guiding assembly 9, the first steel roller 6, and the second steel roller 8 are arranged sequentially along the transmission path of the electrode 5, that is, the electrode 5 passes through the web guiding assembly 9, the first steel roller 6, and the second steel roller 8 in sequence. Due to the clamping of the electrode 5 by the rubber roller 8 and the second steel roller 8, the electrode 5 is tensioned, and the web guiding assembly 9 can better guide the electrode 5.
[0046] In some embodiments, such as Figure 1 and Figure 3 As shown, the frame 1 is provided with an adjusting component 10, and the rubber roller 8 is provided on the adjusting component 10. The adjusting component 10 can adjust the distance between the rubber roller 8 and the second steel roller 7, thereby adjusting the clamping force of the rubber roller 8 and the second steel roller 8 on the electrode sheet 5.
[0047] Specifically, such as Figure 3 As shown, the adjusting component 10 includes a base 101, a sliding component 102, and an adjusting rod 103. The base 101 is fixedly mounted on the frame 1. The sliding component 102 is slidably connected to the base 101. The adjusting rod 103 is rotatably mounted on the frame 1. The adjusting rod 103 has an external thread, and the sliding component 102 has a threaded hole. The adjusting rod 103 extends into the threaded hole and is threadedly connected to the sliding component 102. When the adjusting rod 103 rotates, it can drive the sliding component 102 to slide relative to the base 101, thereby driving the rubber roller 8 to move and adjusting the gap between the rubber roller 8 and the second steel roller 7. The adjusting rod 103 is vertically positioned, and the sliding component 102 can slide up and down relative to the base 101, thereby driving the rubber roller 8 to move up and down.
[0048] In some embodiments, such as Figure 1 As shown, the transmission roller includes a swing roller 20, and a swing arm 30 and a cylinder 40 are provided on the frame 1. The swing arm 30 is rotatably connected to the frame 1, the swing roller 20 is rotatably mounted on the swing arm 30, and the cylinder 40 is mounted on the frame 1 and connected to the swing arm 30. Specifically, when the tension of the electrode 5 needs to be adjusted, the cylinder 40 is controlled by the corresponding control component to extend and retract, thereby driving the swing arm 30 to rotate relative to the frame 1. When the swing arm 30 rotates, it drives the swing roller 20 to move. After the position of the swing roller 20 moves, the tension of the electrode 5 can be adjusted.
[0049] like Figure 1 As shown, the transfer roller also includes several passing rollers 50 located on the transfer path of the electrode 5 to ensure the smooth transfer of the electrode 5.
