Description

Technical Field

[0001] This utility model belongs to the technical field of battery separator production equipment, and in particular relates to a battery separator slitting machine. Background Technology

[0002] Battery separator slitting machine is a key piece of equipment in the front-end process of lithium-ion battery production. Its core function is to precisely slit the wide battery separator master roll into multiple narrow separator strips of equal or unequal width according to the size requirements of the battery cell pack. These slit separator strips will serve as the insulating layer between the positive and negative electrode sheets and will be wound or stacked into battery cells.

[0003] Currently, existing battery separator slitting machines mainly consist of the following basic components: Unwinding and feeding unit: usually a feed roller (or unwinding shaft) is used to carry the diaphragm.

[0004] Slitting unit: This is the core of the equipment, mainly consisting of one or more rigidly mounted cutting blades (such as circular blades or razors) and their corresponding lower cutting grooves or bottom rollers, used to longitudinally cut the diaphragm in motion.

[0005] The winding and unwinding unit is a discharge roller used to discharge multiple slit tapes after slitting.

[0006] However, existing battery separator slitting machines have the following drawbacks in practical use: First, existing equipment lacks a diaphragm anti-deviation mechanism. After long-term use, the diaphragm's running trajectory is prone to deviation. Once the diaphragm deviates, it can cause uneven slitting width at best, and wrinkling and breakage of the diaphragm at the slitting point at worst, generating a large amount of waste and potentially damaging expensive cutting tools. Secondly, the existing equipment lacks a support structure at the cutting position. At the moment of cutting, especially when slitting ultra-thin diaphragms, the diaphragm is prone to local stretching, shaking, or lateral slippage due to stress. This directly leads to burrs, serrated edges ("ruffled edges"), or "stringing" phenomena on the cut. These micro-defects will become stress concentration points in the subsequent battery winding, and may even cause internal short circuit risks.

[0007] Therefore, it is essential to invent a battery separator slitting machine. Utility Model Content

[0008] To address the above problems, this utility model proposes a battery separator slitting machine, and the technical solution used is as follows: A battery separator slitting machine includes a worktable, a feeding roller, anti-deviation frames, guide rollers, and a slitting mechanism. The feeding roller is rotatably mounted on the upper side of one end of the worktable via a support bearing. Two anti-deviation frames are provided on one side of the feeding roller, and both anti-deviation frames are fixed to the worktable by bolts. The slitting mechanism is provided on one side of the anti-deviation frames and is fixed to the upper side of the worktable by bolts. Guide rollers are provided on both sides of the slitting mechanism, and both ends of the guide rollers are rotatably connected to the worktable via support bearings.

[0009] Furthermore, the anti-deviation frame includes an upright plate, side plates, gas nozzles, gas supply pipes, solenoid valves, infrared emitting modules, and infrared receiving modules. The upright plate is fixed to the side of the workbench with bolts, and two side plates are fixed to the side of the upright plate with bolts. Gas nozzles are fixed on each side plate, and the output ends of the gas nozzles face the upright plate between the two side plates. The input ends of the gas nozzles are connected to an external gas supply mechanism through gas supply pipes, and a solenoid valve is fixed in the middle of the gas supply pipe. The solenoid valve is electrically connected to an external production computer through a data cable. Several infrared emitting modules are arranged in a straight line along the upper side plate, and several infrared receiving modules are arranged in a straight line along the lower side plate. Both the infrared emitting and receiving modules are electrically connected to the external production computer through data cables. This arrangement can prevent the diaphragm from shifting during cutting.

[0010] Furthermore, the slitting mechanism includes a lifting mechanism, a cutting mechanism, and a frame. The lifting mechanism is fixed on the worktable in a linear array, and each of the upper sides of the lifting mechanism is correspondingly provided with a cutting mechanism, which is fixed inside the frame. The frame is fixed to the worktable by bolts. In use, the diaphragm passes between the lifting mechanism and the cutting mechanism. The cutting mechanism can cut the diaphragm, while the lifting mechanism can assist in positioning the diaphragm at the cutting position.

[0011] Furthermore, the lifting mechanism includes a first slider, a first roller, a cutting groove, a first stud, and a first nut. The first slider is slidably mounted on the upper side of the worktable, and the first roller is rotatably mounted on the first slider via a support bearing. The outer side of the first roller has a cutting groove. The lower side of the first slider is fixed with a first stud by welding. The first stud is slidably connected to the worktable, and the first nut is threadedly engaged on the first stud located on the lower side of the worktable. This arrangement can prevent the diaphragm from shifting during cutting.

[0012] Furthermore, the cutting mechanism includes a second slider, a cutting blade, a second stud, a second nut, and a second roller. The second slider is slidably installed inside the frame, and the cutting blade is fixed to the lower side of the second slider by bolts. The second stud is fixed to the upper side of the second slider by welding, wherein the second stud is slidably connected to the frame, and the second nut is installed on the outer side of the second stud located on the upper side of the frame by thread engagement. The second rollers are rotatably installed on both sides of the lower end of the second slider through support bearings. With this configuration, the cutting blade can cut the diaphragm. Secondly, by loosening the second nut, different cutting size requirements can be met. In addition, the cooperation between the second roller and the first roller can prevent the diaphragm from shifting during cutting.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this utility model, the anti-deviation frame is designed such that, during use, the diaphragm moves between the two side plates inside the two anti-deviation frames. When the diaphragm's trajectory deviates, the corresponding infrared emitting module and infrared receiving module transmit data to the external production computer. The external production computer then activates the solenoid valve inside the other anti-deviation frame, which causes the gas nozzle inside that anti-deviation frame to spray gas onto the diaphragm. The force of the gas causes the diaphragm to reset. The slitting mechanism of this invention, during use, allows the diaphragm to pass between the lifting mechanism and the cutting mechanism, and the diaphragm is cut by the cutting blade. The lateral position of each slitting unit (individual lifting mechanism and cutting mechanism) can be independently adjusted by simple mechanical adjustments (loosening / locking the first nut and the second nut). This design allows the equipment to quickly adapt to slitting requirements of different width specifications. Furthermore, at the cutting point, the coordinated rotation of the second roller and the first roller forms a dynamic, flexible clamp on the moving diaphragm. This design can suppress diaphragm vibration, stretching, or lateral displacement caused by uneven force during cutting. Attached Figure Description

[0023] Please see Figures 1 to 5 As shown, this utility model is a battery separator slitting machine, including a worktable 1, a feeding roller 2, an anti-deviation frame 3, a guide roller 4, and a slitting mechanism 5.

The slitting mechanism 5 is provided on one side of the anti-deviation frame 3, and the slitting mechanism 5 is fixed to the upper side of the worktable 1 by bolts. Guide rollers 4 are provided on both sides of the slitting mechanism 5, and both ends of the guide rollers 4 are rotatably connected to the worktable 1 through support bearings.

[0024] Specifically, the anti-deviation frame 3 includes a vertical plate 31, side plates 32, gas nozzles 33, gas supply pipes 34, solenoid valves 35, infrared emitting modules 36, and infrared receiving modules 37. The vertical plate 31 is fixed to the side of the workbench 1 by bolts, and two side plates 32 are fixed to the side of the vertical plate 31 by bolts. Gas nozzles 33 are fixed on each side plate 32, and the output ends of the gas nozzles 33 face the vertical plate 31 between the two side plates 32. The input ends of the gas nozzles 33 are connected to an external gas supply mechanism through the gas supply pipes 34, and a solenoid valve 35 is fixed in the middle of the gas supply pipes 34. The solenoid valve 35 is electrically connected to an external production computer through a data cable. The upper side plate 32 has a linear array of... Several infrared emitting modules 36 are arranged, and several infrared receiving modules 37 are arranged in a straight line along the lower side plate 32. The infrared emitting modules 36 and infrared receiving modules 37 are electrically connected to an external production computer via data cables. In use, the diaphragm moves between the two side plates 32 inside the two anti-deviation frames 3. When the diaphragm's trajectory deviates, the corresponding infrared emitting modules 36 and infrared receiving modules 37 transmit data to the external production computer. The external production computer activates the solenoid valve 35 inside another anti-deviation frame 3, which causes the gas nozzle 33 inside the anti-deviation frame 3 to spray gas onto the diaphragm. The force of the gas causes the diaphragm to reset.

[0025] Specifically, the slitting mechanism 5 includes a lifting mechanism 51, a cutting mechanism 52, and a frame 53. The lifting mechanism 51 is fixed on the worktable 1 in a straight line array, and the upper side of the lifting mechanism 51 is provided with a corresponding cutting mechanism 53. The cutting mechanism 52 is fixed inside the frame 53. The frame 53 is fixed on the worktable 1 by bolts. In use, the diaphragm passes between the lifting mechanism 51 and the cutting mechanism 52. The cutting mechanism 52 can cut the diaphragm, while the lifting mechanism 51 can assist in positioning the diaphragm at the cutting position.

[0026] Specifically, the lifting mechanism 51 includes a first slider 511, a first roller 512, a cutting groove 513, a first stud 514, and a first nut 515. The first slider 511 is slidably mounted on the upper side of the worktable 1, and the first roller 512 is rotatably mounted on the first slider 511 via a support bearing. The outer side of the first roller 512 has a cutting groove 513. The lower side of the first slider 511 is fixed with the first stud 514 by welding. The first stud 514 is slidably connected to the worktable 1 and is located under the worktable 1. A first nut 515 is installed on the first stud 514 on the side through thread engagement. With this arrangement, the diaphragm passes through the upper side of the first roller 512 during use, and the first roller 512 can rotate accordingly as the diaphragm moves, thereby supporting the diaphragm and preventing the diaphragm from shifting during cutting. Secondly, when the position of the cutting mechanism 52 changes, the position of this mechanism on the worktable 1 can be adjusted by loosening the first nut 515, so that this mechanism always corresponds to the cutting mechanism 52.

[0027] Specifically, the cutting mechanism 52 includes a second slider 521, a cutting blade 522, a second stud 523, a second nut 524, and a second roller 525.

The lower ends of the second slider 521 are rotatably mounted with second rollers 525 via support bearings on both sides. With this configuration, the cutting blade 522 can cut the diaphragm as it moves during use. Furthermore, the position of this mechanism inside the frame 53 can be adjusted by loosening the second nut 524 to meet different cutting size requirements. In addition, the cooperation between the second roller 525 and the first roller 512 can dynamically clamp the two sides of the diaphragm at the cutting position, thereby preventing the diaphragm from shifting during cutting.

Its working principle is as follows: When in use, the separator passes through the feeding roller 2, the anti-deviation frame 3, the first guide roller 4, the slitting mechanism 5 and the second guide roller 4 in sequence. The separator is moved accordingly by the external unwinding mechanism and the winding mechanism. Then, the separator is slitting by the slitting mechanism 5. The anti-deviation frame 3 can make the separator run along a predetermined trajectory to avoid deviation.
