Description

Technical Field

[0001] The utility model relates to the technical field of storage devices, and more specifically to a sodium ion battery production winding device. Background Art

[0002] A battery separator refers to a layer of separator material between the positive and negative electrodes of a battery. Its main function is to isolate the positive and negative electrodes and prevent electrons in the battery from passing through freely, while allowing ions in the electrolyte to pass freely between the positive and negative electrodes. During production, it needs to be rolled up and wound into rolls for storage and transportation.

[0003] The existing diaphragm production uses a winding frame with a shaft when winding. After winding, the rolled diaphragm needs to be removed from the winding shaft and then rolled next time. Because the existing winding shaft is set horizontally, external force is required to push the diaphragm from the end face when removing it, which makes the end face of the diaphragm easy to bend or even damaged, affecting the quality of the diaphragm. In view of this, we propose a winding device for sodium ion battery production. Utility Model Content

DETAILED DESCRIPTION

[0021] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] This embodiment provides a sodium ion battery production winding device, referring to Figure 1-4 , including a main frame 1, the main frame is welded and assembled by pipe fittings to form a fixed frame structure, providing installation space, when producing the winding equipment, a driving component 7 and a winding component 6 are installed at the lower part of the main frame 1, wherein the driving component 7 is connected to an external motor or a rotating driving member to provide a rotating driving force, and the winding component 6 is used to install a shaft cylinder for winding the produced battery diaphragm, and the driving component 7 is assembled and connected with the main frame 1, and the driving component 7 is rotatably installed on the main frame 1 through a bearing for stable rotation, and at the same time, the winding component 6 can It swings back and forth around the main frame 1. When winding, the winding component 6 is in a horizontal state and can perform stable rotational winding. After the winding is completed, the winding component 6 is driven to tilt forward. At this time, because the winding component 6 is movably connected with the driving component 7, the winding component 6 can tilt forward smoothly, so that the rolled diaphragm on the outside of the winding component 6 automatically slides forward under the action of its own gravity, completing automatic unloading. There is no need to push the diaphragm roll forward from the back side, and the end face of the diaphragm can be avoided from being subjected to force during unloading, which can avoid affecting the quality of the diaphragm during the unloading process.

[0023] Reference Figure 3 The winding assembly 6 includes a winding shaft 61, which adopts a cylindrical straight rod, which can facilitate the forward and backward sliding installation and removal of the shaft tube for winding the diaphragm, and the winding shaft 61 is rotatably connected to a swing frame 63 at one end close to the driving assembly 7. At the same time, a swivel seat 64 is rotatably installed at the lower end of the swing frame 63, and the swivel seat 64 is fixedly connected to the main frame 1. When the front end of the winding shaft 61 is pressed down and swung, the swing frame 63 rotates forward around the swivel seat 64. At this time, the winding shaft 61 installed on the top of the swing frame 63 through the bearing rotation will swing down at the front end, and the diaphragm roll outside the winding shaft 61 can be slid forward and removed.

[0024] Reference Figure 3When winding, the winding shaft 61 is set horizontally to ensure that the diaphragm rotates horizontally and avoids moving back and forth. In addition, when winding, the winding shaft 61 is fixedly installed with a transmission sleeve 62 at one end close to the drive component 7. The rotation of the transmission sleeve 62 can drive the winding shaft 61 to rotate. At the same time, the winding shaft 61 is detachably installed with a limit ring at one end away from the drive component 7. The limit ring can press the shaft tube of the diaphragm to ensure that the diaphragm rotates synchronously with the winding shaft 61 to complete smooth winding. After winding, the limit ring can be removed and the shaft tube can be disassembled by moving forward without hindrance.

[0025] Reference Figure 3 The driving assembly 7 includes a middle frame 71, which has two vertical plate-like structures. A transmission shaft 72 is installed on the plate body at the rear side, wherein the upper part of the middle frame 71 is rotatably connected to the transmission shaft 72 through a bearing, and can rotate smoothly. At this time, a telescopic cylinder 73 is installed on the plate body at the front, that is, the middle part of the middle frame 71. The telescopic cylinder 73 is arranged horizontally front and back, and the rear end is rotatably pin-connected with the plate body at the rear side. The piston rod of the telescopic cylinder 73 is rotatably assembled and connected with the swing frame 63. When the telescopic cylinder 73 is extended, the swing frame 63 can be driven to swing forward, and after the telescopic cylinder 73 is shortened, the swing frame 63 can be driven to swing backward until it is in a vertical state. At this time, the swing frame 63 will be pressed against the front side of the plate body at the front to complete stable positioning.

[0026] Reference Figure 4 In order to ensure the smooth forward and backward swing of the swing frame 63, a universal joint 74 and a linkage shaft 75 are installed in series at one end of the transmission shaft 72 near the transmission sleeve 62. The universal joint 74 can be bent to ensure that there can be an angle between the transmission shaft 72 and the winding shaft 61. The linkage shaft 75 is slidably engaged and plugged with the transmission sleeve 62. During transmission, the tooth groove on the inner wall of the transmission sleeve 62 is engaged with the convex key on the outer wall of the linkage shaft 75, and the transmission is stable. When the winding shaft 61 tilts forward, the linkage shaft 75 is pulled backward a distance from one end of the transmission sleeve 62, and can swing downward synchronously to ensure the smooth swing of the winding shaft 61.

[0027] Reference Figure 2 A symmetrically arranged push roller 4 is installed on the upper part of the main frame 1. The push roller 4 has a tooth groove convex key, which can improve the friction force and realize the smooth pushing of the diaphragm. A reversing roller 5 is installed between the push rollers 4 on the main frame 1. The reversing roller 5 can reverse the diaphragm twice, tighten the diaphragm by friction, and ensure that the diaphragm is in a flat state during winding. When a new shaft cylinder is replaced after winding, the position of the lower end of the diaphragm can be guaranteed to be stable.

[0028] Reference Figure 2A support roller 2 and a flattening frame 3 are installed near the push roller 4 on the main frame 1. When the input diaphragm is relatively flat, it can pass directly from the support roller 2. The friction resistance to the diaphragm is small, which can ensure that the diaphragm passes quickly and is rolled up. When the input diaphragm is relatively curved, the diaphragm is passed through the flattening frame 3. A slower passing speed is used to flatten the diaphragm and then roll it up. The support roller 2 and the flattening frame 3 are symmetrically arranged to facilitate distinguishing the positions.
