DETAILED DESCRIPTION

[0033] The specific implementation of the present application will be described with reference to the accompanying drawings.

[0034] Reference Figure 1 , the figure is a three-dimensional structure schematic diagram of the polar piece cutting dust suction mechanism for the winding equipment, the right side is the winding shaft 6, the polar piece material belt 101 passes through the adjusting roller 1, the rubber roller 2, the cutter assembly 3, the roller 4 and the thread flattening roller 5 in sequence from the left side, and is wound into a material roll 102 at the winding shaft 6; when the material roll is about to be full, the polar piece material belt 101 is cut by the cutter 31 of the cutter assembly 3, and the dust generated in the cutting process is sucked into the dust suction cover 7 and collected into the dust removal machine 8 at the lower left.

[0035] Reference Figures 1 to 7A dust extraction mechanism for cutting electrode sheets in a winding device includes an adjusting roller 1, a rubber roller 2, a cutter assembly 3, a guide roller 4, a threaded flattening roller 5, and a winding shaft 6 arranged sequentially along the travel direction of the electrode sheet strip 101. The electrode sheet strip 101 forms an S-shaped travel between the adjusting roller 1 and the threaded flattening roller 5, and is wound into a roll 102 by the winding shaft 6. The cutter assembly 3 is located at a cutting position 103 between the rubber roller 2 and the guide roller 4. The rubber roller 2 and the guide roller 4 lift the electrode sheet strip 101 at the cutting position 103 upwards. The cutter assembly 3 is located below the electrode sheet strip 101 at the cutting position 103. 3 includes a cutter 31 and a drive cylinder 32. The drive cylinder 32 is connected to the cutter 31 via a swing rod 33. The swing rod 33 is sleeved on both ends of the roller 4. The cutter 31 is movably set in the outer circumferential direction of the roller 4 via the swing rod 33. A dust suction hood 7 is provided below the cutter 31. The dust suction hood 7 has a dust suction port 71 facing the cutter 31. When cutting the electrode strip 101, the drive cylinder 32 drives the cutter 31 to cut the electrode strip 101. The dust generated by cutting the electrode strip 101 is sucked in by the negative pressure of the dust suction port 71 of the dust suction hood 7 and collected into the dust collector 8 through the air duct 81.

[0036] The electrode cutting and dust collection mechanism of this application for a winding equipment drives the cutter 31 to cut the electrode strip 101 by driving the cylinder 32 and the swing arm 33. This allows the cutter 31 to quickly cut the electrode strip 101, reducing the contact time between the cutter 31 and the electrode strip 101, improving the cutting quality, reducing dust generation, and sucking in the dust through the dust collection hood 7. The dust is then collected and filtered by the dust collector 8, achieving a highly efficient dust removal effect.

[0037] In order to fix the cutter 31, in this embodiment, reference is made to Figure 4 The cutter 31 is fixed on the cutter holder 34, and the two ends of the cutter holder 34 are fixedly connected to two swing rods 33.

[0038] Understandably, with this configuration, the cutter 31 is relatively thin and easy to bend. The cutter 31 is fixed by the cutter holder 34, so that the cutter 31 can be set in a straight position at the cutting position 103. At the same time, it ensures that the cutter 31 will not deform during the cutting of the electrode strip 101, thereby improving the cutting quality and consistency. The cutter holder 34 and the swing arm 33 can be fixed with screws, making assembly convenient.

[0039] In order to ensure that the airflow is evenly distributed within the suction port 71, in this embodiment, reference is made to Figure 6 The suction port 71 is funnel-shaped, and multiple through holes 72 are provided at equal intervals on the inner side of the suction port 71. A connecting pipe 73 connected to the air duct 81 is provided parallel to the lower end of the suction hood 7. The connecting pipe 73 and the suction hood 7 are connected through multiple suction holes.

[0040] It can be understood that, in this way, the connecting pipe 73 is parallel to the dust cover 7, the air pipe 81 communicates with the connecting pipe 73, the dust suction port 71 communicates with the connecting pipe 73 through the plurality of through holes 72, and the plurality of through holes 72 introduce the airflow at different positions of the dust suction port 71 into the connecting pipe 73, thereby ensuring uniform distribution of the airflow in the dust suction port and improving the dust suction effect.

[0041] In order to better inhale dust, in the embodiment, referring to Figure 5 and Figure 6 , the lower side of the dust suction port 71 is arranged close to the roller surface of the passing roller 4, an opening 74 is formed between the upper side of the dust suction port 71 and the roller surface, the opening 74 is arranged towards the pole piece material belt 101 at the cutting position 103, and the cutter 31 is movably arranged at the opening 74.

[0042] It should be further explained that the dust cover 7 is made of SUS304 stainless steel, the SUS304 stainless steel has high corrosion resistance, the surface of the SUS304 stainless steel is smooth and easy to clean, and bacteria and other microorganisms are not easy to breed on the surface of the SUS304 stainless steel. The SUS304 stainless steel is not easy to be magnetized in a conventional magnetic field, so that dust is difficult to adhere to the surface of the dust cover 7; the dust suction port 71 is similar to a horn port, and the design of the horn port helps to optimize the distribution of airflow at the cutting position 103, which helps to reduce airflow dead angles and vortex phenomena, so that dust is more easily sucked into the dust cover 7 and collected.

[0043] It can be understood that, in this way, the dust suction port 71 of the dust cover 7 adopts the design of a horn port, which not only pays attention to practicability, but also takes into account aesthetics, can effectively hide the cutter 31, makes the equipment look clean from the outside, and also increases the protection performance of the equipment.

[0044] In order to lift the pole piece material belt 101 at the cutting position 103, in the embodiment, referring to Figures 1 to 5 , the dust cover 7 is fixedly connected with a lifting plate 91 at both ends, the rubber roller 2 and the passing roller 4 are connected with the lifting plate 91, the lifting plate 91 is movably arranged on the rack 9 through a lifting driving assembly 92, the lifting driving assembly 92 includes a lifting screw pair 921, a lifting motor 922 and a lifting guide rail 923, the lifting screw pair 921 and the lifting guide rail 923 are arranged in parallel on the rack 9, the lifting motor 922 is in transmission connection with the lifting screw pair 921, and the lifting motor 922 drives the lifting plate 91 to move along the lifting guide rail 923 through the lifting screw pair 921.

[0045] It can be understood that, in this way, during the winding process, the lifting plates 91 drive the rubber rollers 2, the passing rollers 4 and the cutter assembly 3 to descend by a certain height, so that the rubber rollers 2 and the passing rollers 4 are not in contact with the pole piece material belt 101, thereby reducing the resistance of the pole piece material belt 101. When it is necessary to cut the pole piece material belt 101, the lifting motor 922 drives the two lifting plates 91 to move along the corresponding lifting guide rails 923 through the lifting screw pairs 921, thereby driving the rubber rollers 2, the passing rollers 4 and the cutter assembly 3 to ascend as a whole. The rubber rollers 2 and the passing rollers 4 are in contact with the pole piece material belt 101, thereby lifting the pole piece material belt 101 at the cutting position 103, reducing the swing of the pole piece material belt 101 at the cutting position 103, and the cutter 31 of the cutter assembly 3 can quickly and stably cut the pole piece material belt 101.

[0046] In order to better lift the pole piece material belt 101 by the rubber rollers 2, in the embodiment, referring to Figure 2 , the lifting plate 91 is provided with a swing cylinder 93, the driving end of the swing cylinder 93 is provided with a swing arm 94, the middle part of the swing arm 94 is pivotally connected with the lifting plate 91 through a rotating shaft, and the two ends of the swing arm 94 are respectively connected with the passive cylinder and the rubber roller 2. The swing cylinder 93 drives the rubber roller 2 to swing up and down around the rotating shaft through the swing arm 94.

[0047] It can be understood that, in this way, the pole piece material belt 101 lifted by the rubber rollers 2 and the passing rollers 4 is in an inclined state. By lifting the rubber rollers 2 through the swing cylinder 93 and the swing arm 94, the pole piece material belt 101 on the side of the rubber rollers 2 can be lifted, so that the included angle between the pole piece material belt 101 and the cutter 31 is close to a right angle, thereby ensuring the cutting quality of the cutter 31 on the pole piece material belt 101.

[0048] In order to avoid that the swing angle of the rubber roller 2 is too large, in the embodiment, referring to Figure 2 and Figure 5 , the lifting plate 91 is provided with a limiting block 95 on both sides of the swing arm 94.

[0049] It can be understood that, in this way, the swing cylinder 93 is a pneumatic component. When the air pressure is unstable, the swing cylinder 93 drives the swing arm 94 to swing at different angles, thereby causing the rubber roller 2 to swing at different angles. The limiting block 95 is used to limit the swing range of the swing arm 94, thereby avoiding that the swing angle of the rubber roller 2 is too large and protecting the pole piece material belt 101.

[0050] In order to adjust the walking path of the pole piece material belt 101, in the embodiment, referring to Figure 1The adjusting assembly 96 is arranged on the rack 9 at two points of the adjusting roller 1, and includes an adjusting seat 961, a moving seat 962, a guide rod 963, an adjusting screw 964 and an adjusting handle 965. The adjusting seat 961 is fixed on the rack 9, the moving seat 962 is arranged on one side of the adjusting seat 961, the guide rod 963 and the adjusting screw 964 are arranged between the moving seat 962 and the adjusting seat 961, the adjusting handle 965 is fixed on the end face of the adjusting screw 964, and the two ends of the adjusting roller 1 are connected with the moving seat 962. The adjusting handle 965 drives the adjusting screw 964 to rotate, so as to drive the moving seat 962 and the adjusting roller 1 to move up and down along the guide rod 963.

[0051] It can be understood that, in this way, the pole piece material belt 101 between the adjusting roller 1 and the thread flattening roller 5 is arranged in an S-shaped belt running mode. The adjusting handle 965 and the adjusting screw 964 drive the moving seat 962 and the adjusting roller 1 to move up and down along the guide rod 963, so that the height of the adjusting roller 1 is adjusted according to different models of the pole piece material belt 101, and different models of the pole piece material belt 101 use the corresponding belt running path.

[0052] In order to monitor the winding of the pole piece material belt 101, in the embodiment, referring to Figure 1 and Figure 6 , the rack 9 is provided with a winding diameter monitoring sensor 61 in the outer circumferential direction of the winding shaft 6, and the winding diameter monitoring sensor 61 is arranged towards the winding shaft 6.

[0053] It can be understood that, in this way, as the winding of the material roll 102 continues, the diameter of the material roll 102 gradually increases. The diameter of the material roll 102 is monitored by the winding diameter monitoring sensor 61. When the winding diameter of the material roll 102 reaches a preset value, the winding diameter detector sends a signal to the PLC, the PLC controls the fan and the driving cylinder 32 of the dust removal machine 8, the driving cylinder 32 drives the cutter 31 to cut the pole piece material belt 101, and the running fan generates negative pressure at the dust suction port 71 to suck the dust generated by cutting the pole piece material belt 101.

[0054] In order to collect the dust, in the embodiment, referring to Figure 7 , the dust removal machine 8 includes a collection box 82, the collection box 82 is provided with an air inlet 83 and an air outlet 84, the air inlet 83 is connected with the dust cover 7 through the air pipe 81, the air outlet 84 is connected with a fan (not shown in the figure), the collection box 82 is provided with a filter bag 85 and a filter 86 in the middle, a hopper 87 is arranged below the filter bag 85, the filter 86 is arranged above the filter bag 85, a blowing pipe 88 is arranged above the filter 86, and the air inlet 83 and the air outlet 84 lead to the filter bag 85 and the filter 86 respectively.

[0055] It needs to be further explained that the air pipe 81 is made of PVC material, which is suitable for high corrosion environment. The air pipe 81 transports the dust to the dust collector 8, and the dust is collected and filtered by the dust collector 8, realizing high-efficiency dust removal effect.

[0056] It can be understood that in this way, the dust generated by cutting the pole piece tape 101 is collected by the dust cover 7, sucked into the dust collector 8 through the air pipe 81, and the filter bag 85 and the filter 86 form a two-stage filtering structure to intercept and filter out the dust. The remaining gas is discharged through the filter 86 and the air outlet 84. Among the dust intercepted by the filter bag 85, most of the dust falls into the ash bucket 87 under the action of gravity, and the remaining part is blown off from the collection box 82 to the ash bucket 87 through the blowing pipe 88 in a pulse blowback manner, reducing the risk of blockage of the collection box 82. The collected dust can be conveniently transferred out through the ash valve 89 below the ash bucket 87.

[0057] The embodiment of the application drives the cutting knife 31 to punch the pole piece tape 101 through the driving cylinder 32 and the swing rod 33, so that the cutting knife 31 can quickly cut the pole piece tape 101, reduce the contact time of the cutting knife 31 and the pole piece tape 101, improve the cutting quality, reduce the generation of dust, and suck the dust generated by cutting the pole piece tape 101 into the dust collector 8 through the dust cover 7. When the gas containing dust passes through the collection box 82, the dust is blocked in the collection box 82, and the clean gas is discharged through the air outlet 84, realizing high-efficiency dust removal effect. With the accumulation of dust on the collection box 82, the blowing pipe 88 blows the accumulated dust into the ash bucket 87 in a pulse blowing manner, reducing the risk of blockage of the collection box 82.

[0058] The above is not intended to limit the technical scope of the present application in any way. Any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
