[0026] Example 1

[0027] A battery separator stretching device, such as Figures 1-5 As shown, it includes a frame 1; the frame 1 is provided with an extension mechanism 2, which can perform extension processing on the diaphragm, so that the diaphragm is extended and stretched to both sides.

[0028] Specifically, the extension mechanism 2 comprises a support 201 symmetrically connected on both sides of the top end of the rack 1, the support 201 is fixedly connected with the rack 1, the support 201 can support the entire extension mechanism 2, the fixedly connected support 201 can improve the stability during the extension, and the symmetrically arranged support 201 can keep the extension of both sides of the baffle synchronous during processing, avoiding defects in the processing of the diaphragm due to excessive unilateral extension force. The chain 202 is connected to the support 201, the chain 202 structure can drive the extension traction structure to present a moving track with both ends parallel and the middle inclined. The support rod 203 is fixedly connected to one side of the chain 202, and the air bag 204 is fixedly connected to the bottom end of the support rod 203. The air bag 204 structure as an extension traction structure can improve the traction effect on the diaphragm, the air bag 204 is a flexible structure and provides a downward pressure by compressing the internal gas, realizing the extension traction of the diaphragm, and the air bags 204 on both sides of the diaphragm clamp the diaphragm by the internal gas pressure, and the air bags 204 have the same internal gas pressure, so that the clamping force of different positions on the contact surface of the air bags 204 on both ends on the diaphragm remains the same, and the adjacent air bags 204 are pressed against each other, so that the gap between the air bags 204 is reduced, thereby avoiding defects in the extension of the diaphragm due to the gap between the clamps during the traction process. The driving frame 205 is slidingly connected to the outside of the support rod 203, and the driving frame 205 structure can press the air bag 204 by moving to continuously increase the gas pressure in the air bag 204, realizing the clamping effect.

[0029] Further, the driving frame 205 is an arc-shaped structure, the arc-shaped driving frame 205 can make the inner wall of the driving frame 205 and the air bag 204 mutually fit, thereby improving the pressing effect on the air bag 204, and the bottom end and the adjacent side of the driving frame 205 are in an open state, which can make the air bag 204 expand in the direction of the adjacent air bag 204 or the diaphragm after being pressed, thereby filling the gap between the air bags 204 or improving the clamping force on the diaphragm. The driving groove corresponding to the structure of the support rod 203 is formed in the inner top end of the driving frame 205, the driving groove structure can facilitate the sliding adjustment of the driving frame 205 outside the support rod 203, and the recess is formed in the middle of the side surface of the support rod 203, which can facilitate the storage of the air bag 204 after being pressed.

Limiting wheels 208 are connected to the inner and outer sides of the chain 202. The limiting wheels 208 are rotatably connected to the bracket 201. The limiting wheels 208 can limit the shape of the chain 202, so that the chain 202 and the airbag 204 on the chain 202 can adapt to different positions of the diaphragm side before, during, and after extension and during winding.

[0031] In addition, a limiting frame 209 is fixedly connected to one side of the bracket 201. The limiting frame 209 can limit the support rod 203 and the drive frame 205.

Since the diaphragm processing environment is a dust-free environment, no dust will flow onto the diaphragm surface with the airflow during the air supply process. A heating rod 302 is connected to the bottom of the fan 301, and the end of the heating rod 302 is connected to the limiting frame 209. The heating rod 302 can continuously heat the air near the fan 301, thereby ensuring that the air blown out by the fan 301 is at a higher temperature, thus improving the diaphragm's stretching effect.

When the supporting rod 203 moves to the limiting frame 209, the supporting rod 203 moves along the sliding groove 210 on the limiting frame 209, and the arc structure at the bottom of the limiting frame 209 drives the driving frame 205. The driving frame 205 moves downward and continuously compresses the air bag 204, and the air bag 204 expands to both sides and the bottom after being extruded. At the same time, the continuously moving chain 202 pulls the continuously moving diaphragm to both sides through the air bag 204, so as to stretch the diaphragm. The stretched diaphragm can be wound by the winding roller 306.
