Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, and in particular to a winding machine with a large-width diaphragm and a high-strength winding roller. Background Art

[0002] Large-width diaphragms usually refer to diaphragm materials with a width significantly larger than conventional sizes used in battery manufacturing, optoelectronics industry, packaging materials, thin-film solar cells and other fields. Diaphragms play a vital role in these applications. For example, in lithium-ion batteries, the diaphragm is responsible for isolating the positive and negative electrodes of the battery, allowing lithium ions to pass through while preventing direct electron transfer to prevent short circuits. Its performance directly affects the safety, energy density and cycle life of the battery. The large width of the large-width diaphragm requires the winder to have a stronger support structure and more precise tension control capabilities. The winding roller is generally made of high-strength and high-rigidity materials, such as special alloy steel or carbon fiber reinforced composite materials, to withstand the huge tension generated by the large-width diaphragm during high-speed winding, to ensure the stability of the winding process and reduce deformation and damage. During the winding process, the winding roller needs to maintain the conveying direction of the coil to ensure the winding quality of the coil. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0054] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0055] Reference Figure 1 to Figure 10 , which is the first embodiment of the utility model, proposes a winding machine with a large-width diaphragm high-strength winding roller, including a frame 1; there are multiple winding rollers 2, and the multiple winding rollers 2 are rotatably arranged on the frame 1, and the side walls of the winding roller 2 are provided with a slot 205, and there are multiple slots 205, and the multiple slots 205 are distributed at intervals on the winding roller 2; both ends of the winding roller 2 are rotatably provided with a guide ring 6; the clamping member 7 is arranged on the guide ring 6, and after the guide ring 6 rotates, the clamping member 7 is engaged with or unengaged with the slot 205.

[0056] In this embodiment, in order to solve the problem in the related art that it is inconvenient to guide the diaphragm when winding the wide diaphragm, a slot 205 is provided on the side wall of the winding roller 2, and a clamp 7 is installed on the guide ring 6. After the clamp 7 is clamped in the slot 205, the positions of the guide ring 6 and the winding roller 2 are relatively fixed. At this time, the wide diaphragm can be guided by the guide ring 6 during the winding process, thereby improving the winding quality. By adjusting the position of the clamp 7 in different slots 205, the guide ring 6 can guide the wide diaphragms of different widths.

[0057] Furthermore, the winding roller 2 includes a first support member 201, which is relatively rotatably arranged on the frame 1; a second support member 202 is relatively rotatably arranged on the frame 1, and the first support member 201 and the second support member 202 are coaxially arranged; there are multiple plug-in shafts 203, and the multiple plug-in shafts 203 are plugged in sequence, the first support member 201 and the second support member 202 are respectively connected to the two plug-in shafts 203 located on both sides, and the card slot 205 is located on the plug-in shaft 203.

[0058] In this embodiment, in order to solve the problem in the related art that the winding roller 2 of the large-width diaphragm has a large span and is prone to bending and deformation, which affects the stable operation of the winding device, the winding roller 2 is set to be a split form consisting of a first support member 201, a second support member 202 and a plurality of plug-in shafts 203. After the plurality of plug-in shafts 203 are plugged together, the first support member 201 and the second support member 202 are plugged in at the head and tail respectively. The first support member 201, the second support member 202 and the plug-in shaft 203 are all processed separately, and the processing size is easier to control, the processing error is small, and the precision is high, which reduces the processing error caused by the large span of the winding roller 2, making it easier to control the tension of the large-width diaphragm during the winding process, and the diaphragm can be evenly wound in the width direction, and the winding quality is better.

[0059] Specifically, the frame 1 is provided with a plurality of winding rollers 2 for winding and tensioning the wide-width diaphragm during winding. Each winding roller 2 is formed by the first support member 201, the second support member 202 and a plurality of plug-in shafts 203. The split design improves the processing accuracy of the winding roller 2, makes the cylindricality of the winding roller 2 higher, reduces the unbalanced moment of inertia generated by the winding roller 2 during the rotation process, improves the stability of the winding roller 2 during rotation, and thus facilitates the control of the tension during the winding of the wide-width diaphragm, and improves the winding quality of the wide-width diaphragm. After a period of use, the severely worn plug-in shafts 203 can be replaced in sections and partitions to further reduce maintenance costs.

[0060] Furthermore, it also includes a support shaft 3 , which is rotatably arranged on the frame 1 , and the first support member 201 , a plurality of plug-in shafts and the second support member 202 are all arranged on the support shaft 3 .

[0061] In this embodiment, in order to further improve the supporting performance of the winding roller 2 and make the winding roller 2 more stable during rotation, a support shaft 3 is also arranged on the frame 1. The support shaft 3 can pass through the first support member 201, the second support member 202 and the plug-in shaft 203 in sequence, so that the supporting performance of the winding roller 2 is more stable.

[0062] Further, the first support member 201 includes a first end cover 2011, which is rotatably set on the support shaft 3; one end of the first support cylinder 2012 is set on the first end cover 2011; the first limiting cylinder 2013 is set at the other end of the first support cylinder 2012, and a first limiting step 2014 is formed between the first support cylinder 2012 and the first limiting cylinder 2013, and the first limiting step 2014 is located on the inner side of the first limiting cylinder 2013.

[0063] In this embodiment, the first support member 201 is composed of a first end cover 2011, a first support tube 2012 and a first limiting tube 2013, wherein a first limiting step 2014 is formed between the first support tube 2012 and the first limiting tube 2013, that is, a stepped structure is formed, which makes it more convenient to connect the first support member 201 and the plug-in shaft 203. During the connection, the first limiting step 2014 can also play a limiting role to avoid deformation of the first support tube 2012 due to the extrusion of the plug-in shaft 203 during the installation process.

[0064] Furthermore, the second support member 202 includes a second end cover 2021, which is rotatably set on the support shaft 3; one end of the second support cylinder 2022 is set on the second end cover 2021; the second limiting cylinder 2023 is set at the other end of the second support cylinder 2022, and a second limiting step 2024 is formed between the second support cylinder 2022 and the second limiting cylinder 2023, and the second limiting step 2024 is located on the outer side of the second limiting cylinder 2023.

[0065] In this embodiment, the second support member 202 is composed of a second end cover 2021, a second support tube 2022 and a second limiting tube 2023, wherein a second limiting step 2024 is formed between the second support tube 2022 and the second limiting tube 2023, but is different from the first limiting step 2014. The second limiting step 2024 is located on the outside of the second limiting tube 2023. Through the different settings of the first limiting step 2014 and the second limiting step 2024, the two ends of the plug-in shaft 203 have corresponding different structures respectively. In this way, after multiple plug-in shafts 203 are connected end to end in sequence, they can be matched with the first limiting step 2014 and the second limiting step 2024. There is no need to set different forms of plug-in shafts 203, which reduces the types of processed parts and thus controls the production cost of the winder.

[0066] Furthermore, the plug-in shaft 203 is a hollow shaft, and the two ends of the plug-in shaft 203 respectively have a third limit step 2031 and a fourth limit step 2032, and the two adjacent third limit steps 2031 and fourth limit steps 2032 are plugged in, and the first limit step 2014 and the second limit step 2024 are respectively plugged in the third limit step 2031 and the fourth limit step 2032 located on both sides.

[0067] In this embodiment, the plug-in shaft 203 is hollow, which can reduce the weight of the winding roller 2. In this way, even if there is a certain processing error in the plug-in shaft 203, the unbalanced rotational inertia generated during the rotation of the plug-in shaft 203 will be greatly reduced, thereby improving the stability of the winding roller 2 during rotation. The plug-in shaft 203 has a third limiting step 2031 and a fourth limiting step 2032 at both ends, respectively. The connection of the entire winding roller 2 is achieved through the cooperation between the first limiting step 2014, the second limiting step 2024, the third limiting step 2031 and the fourth limiting step 2032. During the installation of the winding machine, since the winding roller 2 adopts a split design, the use of hoisting equipment can be reduced when assembling the winding roller 2, and the operating intensity of the installer can also be reduced. The installer only needs to plug the first support member 201, the plug-in shaft 203 and the second support frame 401 on the support shaft 3 in sequence. It is convenient for installation, maintenance and replacement, and further reduces the maintenance cost of the equipment.

[0068] Furthermore, the first limiting step 2014, the second limiting step 2024, the third limiting step 2031 and the fourth limiting step 2032 all have limiting grooves 204, and also include a limiting member 4. After the first support member 201, the multiple plug-in shafts 203 and the second support member 202 are plugged in, the two ends of the limiting member 4 are plugged into the two connected limiting grooves 204.

[0069] In this embodiment, in order to further improve the stability of the first support member 201, the plug-in shaft 203 and the second support member 202 after being plugged in, the first limiting step 2014, the second limiting step 2024, the third limiting step 2031 and the fourth limiting step 2032 are all provided with limiting grooves 204. After the first support member 201 and the plug-in shaft 203 are plugged in, after the two plug-in shafts 203 are plugged in together and after the plug-in shaft 203 and the second support member 202 are plugged in together, two adjacent limiting grooves 204 are connected, and the limiting member 4 can be inserted into the connected limiting grooves 204. The limiting member 4 can not only improve the stability of the connection of the winding roller 2, but also support the winding roller 2 in the winding roller 2, further improve the support of the winding roller 2, make the winding roller 2 more stable during the rotation process, and reduce the bending deformation of the winding roller 2 caused by the large span.

[0070] Furthermore, the limiting member 4 includes a support frame 401, which is arranged on the support shaft 3; the support ring 402 abuts against the inner wall of the plug-in shaft 203; the two ends of the support rod 403 are respectively arranged on the support frame 401 and the support ring 402; one end of the limiting rod 404 is slidably arranged on the support frame 401, and the other end of the limiting rod 404 passes through the support ring 402. After the limiting rod 404 extends out of the support ring 402, it is located in the two connected limiting grooves 204.

[0071] In this embodiment, the support frame 401 of the limit member 4 is arranged on the support shaft 3, and the support rod 403 connects the support frame 401 and the support ring 402, wherein the support ring 402 can abut against the inner wall of the plug-in shaft 203, further improving the support performance of the limit member 4. The limit rod 404 is slidably arranged on the support frame 401, and the limit rod 404 can enter the limit groove 204 or withdraw from the limit groove 204 after sliding. When the first support member 201, the plug-in shaft 203 and the second support member 202 are plugged together in sequence, the limit rod 404 is slid into the connected limit groove 204, so that the connection of the two plugged together can be more stable. When the plug-in shaft 203 needs to be replaced, the limit rod 404 is slid to withdraw the limit rod 404 from the limit groove 204.

[0072] Furthermore, it also includes a cam 405, which is rotatably arranged in the support frame 401, and the cam 405 has crests 4051 and troughs 4052, and one end of the limiting rod 404 alternately abuts against the crests 4051 and the troughs 4052; the two ends of the first elastic member 406 are respectively arranged on the support ring 402 and the limiting rod 404.

[0073] In this embodiment, the cam 405 has a crest 4051 and a trough 4052, and a first elastic member 406 is connected between the limiting rod 404 and the support ring 402. By rotating the cam 405, one end of the limiting rod 404 can slide between the crest 4051 and the trough 4052, thereby pushing the limiting rod 404 to slide, so that one end of the limiting rod 404 enters the limiting groove 204, or the limiting rod 404 is reset under the action of the first elastic member 406, that is, withdraws from the limiting groove 204. Two groups of limiting holes are provided on the limiting plate 407, and the limiting rod 404 can pass through the limiting holes. The two groups of limiting holes are respectively used to limit the position of the cam when the limiting rod 404 extends into the limiting groove 204 or withdraws from the limiting groove 204, so that the position of the limiting rod 404 can remain stable.

[0074] Furthermore, it also includes a protective cover 5 , which is rotatably arranged on the plug-in shaft 203 , the plug-in shaft 203 is covered in the protective cover 5 , and the guide rings 6 are located at both ends of the protective cover 5 .

[0075] In this embodiment, in order to improve the quality of winding and prevent the wide diaphragm from being scratched by the plugging point of the first support member 201, the plugging shaft 203 and the second support member 202 during the winding process, a protective cover 5 is also provided on the plugging shaft 203. The protective cover 5 is rotatably provided on the plugging shaft 203, which can further reduce the resistance during winding. The guide ring 6 guides the wide diaphragm on both sides of the protective cover 5, further improving the quality of winding.
