Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically, to a multi-directional adjustable hot-cutting device for battery core separators. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the opposite occurs during discharging. In the production process of lithium-ion batteries, the separator of the battery core needs to be precisely cut to complete the slitting process. In existing technologies, separator cutting is generally carried out by mechanical cold cutting, which can easily lead to burrs or delamination of the separator after cutting, thereby reducing battery performance. Based on this, this invention designs a multi-directional adjustable hot cutting device for battery core separators to solve the above problems. Summary of the Invention

[0011] Beneficial effects Compared with the prior art, the advantages of this invention are: In this invention, by incorporating a heating wire, the device can thermally cut the separator by heating a hot-cutting blade, thereby preventing burrs or delamination at the cut edge and improving battery performance. Simultaneously, by incorporating a temperature control component, the device can automatically control the rotation of a threaded rod when driving the hot-cutting blade downwards. This allows the device to adjust the heating power of the heating wire according to the thickness of the separator below the hot-cutting blade, thus regulating the heating temperature of the hot-cutting blade and preventing it from becoming too high or too low, thereby improving the thermal cutting effect on the separator.

[0012] In this invention, by setting a cooling component, the device can automatically control the rotation of two rotating shafts after the diaphragm is hot-cut, thereby allowing the two fan blades to cool the cut area of ​​the diaphragm, so that the molten area at the cut can be quickly solidified and prevented from flowing, sagging or deforming under gravity or accidental contact, thus ensuring the flatness and preset shape of the cut edge.

[0013] In this invention, by setting up a cleaning component, the device can automatically control the rotation of the fixed rod when cooling the diaphragm, thereby causing the coil spring two to twist and store force. When the hot cutting blade moves to the initial position, the elastic force of the coil spring two will drive the circular gear two to reverse, thereby causing the threaded rod two to drive the movable seat to move. This allows the device to clean the outside of the hot cutting blade with an anti-static brush, preventing the molten diaphragm from the previous cutting from adhering to the outside of the hot cutting blade, thus facilitating the next hot cutting and further improving the hot cutting effect.

[0020] By setting up the cooling component 7, the device can automatically control the rotation of the two rotating shafts 72 after the diaphragm is hot-cut, thereby allowing the two fan blades 73 to cool the cut part of the diaphragm so that the molten area at the cut part can be quickly solidified and prevented from flowing, sagging or deforming under gravity or accidental touch, thus ensuring the flatness and preset shape of the cut edge.

[0021] The cleaning component 8 includes a guide groove 81 formed on the outside of the connecting box 5. A movable seat 82 is slidably connected to the inner cavity of the guide groove 81.

[0022] By setting up the cleaning component 8, the device can automatically control the rotation of the fixed rod 813 when cooling the diaphragm, thereby causing the coil spring 817 to twist and store force. When the hot cutting blade 10 moves to the initial position, the elastic force of the coil spring 817 will drive the circular gear 812 to reverse, thereby causing the threaded rod 83 to drive the movable seat 82 to move. This allows the device to clean the outside of the hot cutting blade 10 with the anti-static brush 85, preventing the molten diaphragm from the previous cutting from adhering to the outside of the hot cutting blade 10, thus facilitating the next hot cutting and further improving the hot cutting effect.

[0023] Working principle of the invention: First, the control adjustment device 1 is activated to adjust the hot cutting blade 10 to the target position. The telescopic rod 9 and power supply 62 are then activated, causing the telescopic rod 9 to push the hot cutting blade 10 downwards. At this time, the hot cutting blade 10 drives the winding wheel 615 to rotate via the connecting rope. This causes the winding wheel 615 to twist and store force, simultaneously driving the circular gear 614 to rotate. The circular gear 614 then drives the ratchet assembly 616 to rotate. At this time, the ratchet assembly 712 is not activated. When the ratchet assembly 616 rotates, it drives the mounting shaft 617 to rotate, causing the mounting shaft 617 to rotate the drive wheel 618, which is fixedly connected to it. When the drive wheel 618 rotates, it drives the driven wheel 618 via the belt 619. The driven wheel 620 rotates, causing the driven wheel 620 to drive the drive shaft 621 fixedly connected to it to rotate. When the drive shaft 621 rotates, it drives the threaded rod 68 fixedly connected to it to rotate, which in turn causes the threaded rod 68 to drive the threaded seat 67 threadedly connected to it to move. When the threaded seat 67 moves, it drives the movable plate 66 fixedly connected to it to move synchronously, which causes the movable plate 66 to drive the conductive plate 65 fixedly connected to it to slide on the resistor 63, so as to adjust the heating power of the heating wire 11 by changing the resistance. When the hot cutting blade 10 contacts the diaphragm, the power supply 62 is stopped. This allows the device to adjust the heating power of the heating wire 11 according to the thickness of the diaphragm, thereby adjusting the heating temperature of the heating wire 11 and avoiding excessively high or low temperatures that would reduce the hot cutting effect. After the hot cutting is completed, when the hot cutting blade 10 moves upward, the coil spring 612 will cause the circular gear 614 to reverse due to its elasticity. This causes the circular gear 614 to drive the ratchet assembly 712, which meshes with it, to rotate. At this time, the ratchet assembly 616 is not working. When the ratchet assembly 712 rotates, it will drive the belt 711, which is fixedly connected to it, to rotate. This belt 711 will drive the drive wheel 710, which is fixedly connected to it, to rotate. When the drive wheel 710 rotates, it will drive the driven wheel 713, which will rotate through the driven gear 79. This will cause the driven wheel 713 to rotate. The connecting rod 77, which is fixedly connected to it, rotates. When the connecting rod 77 rotates, it drives the driving gear 78, which is fixedly connected to it, to rotate. This drives the driven gear 79, which meshes with it, to rotate. When the driven gear 79 rotates, it drives the rotating shaft 72, which is fixedly connected to it, to rotate. This drives the rotating shaft 72 to rotate through the transmission wheel 74 and the transmission belt 75. When the two rotating shafts 72 rotate, they synchronously drive the fan blades 73, which are fixedly connected to them, to rotate. This allows the fan blades 73 to cool and shape the hot-cut part of the diaphragm. When the rotating shaft 72 rotates, it drives the second driving gear 815, which is fixedly connected to it, to rotate. This causes the second driving gear 815 to drive the driven gear 814, which meshes with it, to rotate. The driven gear 814, in turn, drives the fixed rod 813, which is fixedly connected to it, to rotate. This causes the fixed rod 813 to twist and store energy through the coil spring 817, which is fixedly connected to it. When the hot cutting blade 10 moves to its initial position, the fixed rod 813, under the elastic force of the circular gear 812, drives the circular gear 812, which is fixedly connected to it, to rotate in reverse. At this time, the circular gear 812 drives the ratchet assembly 811, which meshes with it, to rotate. This causes the ratchet assembly 811 to drive the mounting rod 8, which is fixedly connected to it, to rotate. When the mounting rod 810 rotates, it drives the drive wheel 89, which is fixedly connected to it, to rotate. This drives the driven wheel 87, which in turn drives the driven wheel 87, which in turn drives the linkage shaft 86, which is fixedly connected to it, to rotate. This drives the threaded rod 83, which is fixedly connected to it, to rotate. This drives the movable seat 82, which is threaded to it, to move. This causes the movable seat 82 to move the U-shaped frame 84, which is fixedly connected to it, to move synchronously. As the U-shaped frame 84 moves, it cleans the outside of the hot cutting blade 10 with the anti-static brush 85, thus preventing the molten diaphragm from the previous cut from adhering to the outside of the hot cutting blade 10.
