Description

Technical Field

[0001] This utility model relates to the field of lithium battery separator production technology, specifically a thin film flattening device for lithium battery separator production lines. Background Technology

[0002] Lithium-ion battery separators are materials used to isolate the positive and negative electrodes. They prevent direct contact between the positive and negative electrodes, thus preventing short circuits, while allowing lithium ions to move freely within the battery. Lithium-ion battery separator production lines require the use of film flattening devices to flatten the lithium-ion battery separators.

[0003] However, most of the existing thin film flattening devices used in lithium battery separator production lines are unable to flatten the lithium battery separator to be flattened from the middle to both sides at a uniform speed, resulting in poor flattening effect.

[0004] To address the aforementioned issues, this application proposes a thin film flattening device for lithium battery separator production lines. Utility Model Content

[0005] In order to solve the problem that most existing film flattening devices used in lithium battery separator production lines cannot flatten the lithium battery separator to be flattened synchronously from the middle to both sides at a uniform speed, the purpose of this utility model is to provide a film flattening device for lithium battery separator production lines.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a film flattening device for a lithium battery separator production line, including a base frame, with guide rollers rotatably inserted into both sides of the top of the base frame, and a flattening mechanism for cooperating with the guide rollers on the base frame. The flattening mechanism includes an electric push rod, which is fixedly installed in the middle of the top of the base frame, and the output end of the electric push rod slides through the base frame and is fixedly sleeved with a bracket at its end. A countersunk hole is opened at the top of the bracket, and the end of the output end of the electric push rod is fixedly inserted into the countersunk hole. The bracket is slidably connected to the base frame, and a rotating shaft, a rotating rod, and a rotating column are rotatably inserted into the bracket. A rotating hole one is opened through the bracket, and the rotating shaft is rotatably inserted into the rotating hole one. A rotating hole two is opened through the lower end of the bracket, and the rotating rod is rotatably inserted into the rotating hole two. Both ends of the bracket are through-cut... There is a rotating hole three, and the rotating column is inserted into the rotating hole three. A gear one and a synchronous pulley one are fixedly sleeved on the rotating shaft, and a synchronous pulley two and another synchronous pulley one are fixedly sleeved on the rotating rod. The rotating column has a symmetrical structure, and a synchronous pulley three is fixedly sleeved on the rotating column. A synchronous belt one is sleeved on the outer side of the adjacent synchronous pulley three and synchronous pulley one, and an array of arc-shaped baffles is fixedly installed on the synchronous belt one. A servo motor is fixedly installed on one side of the bracket, and the output end of the servo motor rotates through the bracket and a gear two and a synchronous pulley four are fixedly sleeved on its outer side. A side frame is fixedly installed on the bracket, and the servo motor is fixedly inserted into the side frame. An insertion hole is opened through the upper end of the bracket, and the side frame is fixedly inserted into the insertion hole. Gear two meshes with gear one, and a synchronous belt two is sleeved on the outer side of synchronous pulley four and synchronous pulley two.

[0007] Preferably, the top of the bracket is fixedly installed with symmetrically arranged guide rods, and the top of the base frame is provided with symmetrically distributed guide holes, and the guide rods slide through the guide holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting and using the flattening mechanism, the two sets of synchronous pulleys one and three can be driven to rotate synchronously, which in turn can drive the two sets of synchronous belts one and the arc-shaped plate to rotate synchronously. This allows the lithium battery separator to be flattened to be moved from the middle to both sides at a uniform speed, thereby effectively improving the flattening effect of the lithium battery separator. 2. The guide rod and guide hole work together to limit and guide the lifting of the bracket, thus ensuring the steady lifting and lowering adjustment of the flattening mechanism.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figures 1-5As shown, this utility model provides a film flattening device for a lithium battery separator production line, including a base frame 1. Guide rollers 2 are rotatably inserted into both sides of the top of the base frame 1. A flattening mechanism 3, which works in conjunction with the guide rollers 2, is provided on the base frame 1. The flattening mechanism 3 includes an electric push rod 31, which is fixedly installed at the middle of the top of the base frame 1. The output end of the electric push rod 31 slides through the base frame 1 and is fixedly sleeved with a bracket 32 ​​at its end. A countersunk hole 316 is provided at the top of the bracket 32, and the output end of the electric push rod 31 is fixedly inserted into the countersunk hole 316. The countersunk hole 316 provides a stable connection between the electric push rod 31 and the bracket 32. To ensure stability, bracket 32 ​​is slidably connected to base frame 1, and a rotating shaft 33, rotating rod 34, and rotating column 35 are rotatably inserted into bracket 32. A first rotating hole 317 is provided through bracket 32, and the rotating shaft 33 is rotatably inserted into rotating hole 317. A second rotating hole 318 is provided through the lower end of bracket 32, and the rotating rod 34 is rotatably inserted into rotating hole 318. Third rotating holes 319 are provided through both ends of bracket 32, and the rotating column 35 is rotatably inserted into rotating hole 319. The arrangement of rotating holes 317, 318, and 319 ensures the stable rotation of rotating shaft 33, rotating rod 34, and rotating column 35. A fixed... A gear 36 and a synchronous pulley 37 are fitted together, and a synchronous pulley 38 and another synchronous pulley 37 are fixedly fitted onto the rotating rod 34. The rotating column 35 has a symmetrical structure, and a synchronous pulley 39 is fixedly fitted onto the rotating column 35. A synchronous belt 310 is fitted onto the outer side of the adjacent synchronous pulley 39 and synchronous pulley 37, and an array of arc-shaped baffles 311 are fixedly installed on the synchronous belt 310. The arc-shaped baffles 311 installed on the two synchronous belts 310 face opposite directions. A servo motor 312 is fixedly installed on one side of the bracket 32, and the output end of the servo motor 312 rotates through the bracket 32 ​​and a gear 31 is fixedly fitted onto its outer side. 3. A side frame 320 is fixedly installed on the bracket 32 ​​and the synchronous pulley 314. The servo motor 312 is fixedly inserted into the side frame 320. The upper end of the bracket 32 ​​has a through hole 321, and the side frame 320 is fixedly inserted into the through hole 321. The cooperation between the through hole 321 and the side frame 320 ensures the stable installation of the servo motor 312. The servo motor 312 and the electric push rod 31 are both controlled by the PLC control module to start and stop. This is the prior art and will not be described in detail here. Gear 2 313 meshes with gear 1 36, and the synchronous pulley 4 314 and the outer side of synchronous pulley 2 38 are meshed with the synchronous belt 2 315.

[0018] By adopting the above technical solution, during use, the electric push rod 31 will drive the bracket 32 ​​to move down, thereby driving the arc-shaped lever 311 to move down. When the arc-shaped lever 311 at the bottom is in contact with the lithium battery separator to be flattened and is in a suitable tension state, the electric push rod 31 will close. Then, the servo motor 312 will drive the synchronous wheel 4 314 and the gear 2 313 to rotate, thereby driving the synchronous wheel 2 38 to rotate through the synchronous belt 2 315. In turn, the rotating rod 34 will drive the corresponding synchronous wheel 1 37 and the synchronous wheel 39 to rotate, thereby driving the corresponding synchronous belt 1 310 and the arc-shaped lever 311 to rotate synchronously. The gear 1 36 will drive the rotating shaft 33 to rotate synchronously in reverse, thereby driving the corresponding synchronous wheel 1 37 and the synchronous wheel 39 to rotate synchronously in reverse, thereby driving the corresponding synchronous belt 1 310 and the arc-shaped lever 311 to rotate synchronously in reverse. This will allow the lithium battery separator to be flattened to be uniformly and synchronously moved from the middle to both sides.

[0019] The top of the bracket 32 ​​is fixedly installed with symmetrically arranged guide rods 4, and the top of the base frame 1 is provided with symmetrically distributed guide holes 11, and the guide rods 4 slide through the guide holes 11.

[0020] By adopting the above technical solution, the guide rod 4 and the guide hole 11 work together to limit and guide the lifting and lowering of the bracket 32, thereby ensuring the steady lifting and lowering adjustment of the flattening mechanism 3.

[0021] Working principle: In use, the lithium battery separator to be flattened is passed through the upper ends of the two guide rollers 2 and its ends are fixed to the winding mechanism. Then, the electric push rod 31 drives the bracket 32 ​​to move down, thereby driving the arc-shaped baffle 311 to move down. When the arc-shaped baffle 311 at the bottom is in contact with the lithium battery separator to be flattened and is in a suitable tension state, the electric push rod 31 closes. Then, the servo motor 312 drives the synchronous pulley 4 314 and gear 2 313 to rotate, thereby driving the synchronous pulley 2 38 to rotate through the synchronous belt 2 315, and thus... The rotating rod 34 drives the corresponding synchronous pulley 37 and synchronous pulley 39 to rotate, which in turn drives the corresponding synchronous belt 310 and arc-shaped baffle 311 to rotate synchronously. The gear 36 drives the rotating shaft 33 to rotate synchronously in reverse, which in turn drives the corresponding synchronous pulley 37 and synchronous pulley 39 to rotate synchronously in reverse, which in turn drives the corresponding synchronous belt 310 and arc-shaped baffle 311 to rotate synchronously in reverse. This allows the lithium battery separator to be flattened to be uniformly flattened from the center to both sides, thus effectively improving the flattening effect of the lithium battery separator.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
