Description

Technical Field

[0001] This invention relates to the field of battery winding molding equipment technology, specifically to a carbon fiber filler material winding molding device. Background Technology

[0002] Battery winding is a process of assembling battery cells into a battery through a winding method. A wound battery is also called a battery cell. Battery winding is generally achieved by a winding machine.

[0003] The advantages of carbon fiber as a battery filler material include:

[0004] 1. Lightweight: Carbon fiber composites have a lower density than metals and even lower density than plastics, but their strength is in no way inferior.

[0005] 2. Stable performance: Carbon fiber composite materials offer strong impact and corrosion resistance, effectively isolating the battery module from the external environment and ensuring the battery is not corroded during operation. Simultaneously, the carbon fiber battery casing also prevents contact between people and the battery, enhancing safety.

[0006] In the prior art, on the one hand, the battery coating material is placed on the coating roller and the battery electrode is placed on the electrode roller. Then, the coating roller and the electrode roller are driven to rotate so that the battery electrode is pressed onto the battery coating by the guide roller. Then, the carbon fiber battery core electrode is placed inside the core-wrapping transmission mechanism and clamped and fixed by the clamp. The carbon fiber battery core electrode is wound around the battery coating by rotating the clamp.

[0007] However, in practical use, the equipment involved in battery winding, such as the main shaft, winding mechanism, and core clamping seat inside the winding machine, requires multiple power supplies, making it impossible to optimize the power supply between the main shaft and the winding mechanism. This leads to increased battery winding costs, which need to be optimized. To address this, we propose a carbon fiber filler material winding molding device. Summary of the Invention

[0013] Preferably, the cutting mechanism includes a cutting mechanism box, a cutting blade holder, a cutting blade, a gear A, and a rack A. The cutting mechanism box is fixedly connected to the cylinder. A motor four is fixedly connected to the side of the cutting mechanism box away from the cylinder. The output end of the motor four passes through the cutting mechanism box and is fixedly connected to the gear A. The rack A is provided with two sets, both of which are meshed with the gear A. The rack A is fixedly connected to the cutting blade through the cutting blade holder.

[0014] Preferably, a connecting arm is provided on one side of the lead screw nut, and the end of the connecting arm away from the lead screw nut is fixedly connected to the core clamp. The lead screw nut is movably connected to the connecting arm through a rotation protection mechanism.

[0015] Preferably, the rotation protection mechanism has an outer ring and an inner ring. The outer ring is fixedly connected to the inner ring by a fixing rod, and the inner ring is fixedly connected to a lead screw nut.

[0016] Preferably, the cutting blade holder is provided in two sets, and the cutting blades fixed to one side of the two sets of cutting blade holders have overlapping projections.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Since the motor is fixedly connected to the main shaft, the main shaft is fixedly connected to the drive gear, and the lead screw is fixedly connected to the main shaft, the purpose of rotating the winding mechanism and adjusting the distance between the winding mechanism and the core-wrapping transmission mechanism can be achieved through the motor, which effectively saves energy consumption in the winding operation, saves production costs, and enhances the market competitiveness of battery products.

[0022] 2. The controller drives the motor to rotate gear B, which in turn moves the two racks B that mesh with it, thus moving the two racks B away from or towards each other. The distance between the two sets of winding clamps can be adjusted. The winding clamps are easy, quick and precise to adjust, and the clamping offset is small, which effectively avoids the problem of the winding clamps causing the carbon fiber battery core to shift during the clamping process.

[0023] 3. The core-coated transmission mechanism is convenient and quick to operate when clamping the carbon fiber battery core. Since the polygonal clamp is set as a regular octagon, the included angle between the extension lines of each pair of adjacent locking rods is 45°. Therefore, the clamping stress of the polygonal clamp on the carbon fiber battery core is uniform, avoiding the phenomenon of carbon fiber battery core displacement caused by uneven clamping stress. This further improves the stability of the carbon fiber battery core clamping and ensures the quality of carbon fiber battery core winding.

[0024] 4. The overlapping projections of the cutting blades fixed on one side of the two sets of cutting blade holders ensure that the battery is not deviated during the cutting operation, effectively guaranteeing the quality of battery cutting. In addition, the end cap can prevent the lead screw nut from moving to one end of the lead screw and detaching from the lead screw during the movement of the lead screw. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-9 This invention provides a technical solution: a carbon fiber filler material winding molding device, including a winding machine 1, a winding mechanism 2, a cutting mechanism 3, and a cylinder 4. The outer side of the winding machine 1 is fixedly connected to a coating roller 11, an electrode roller 12, a controller 13, a guide roller 14, and a motor 15. The winding mechanism 2 is provided with a main shaft 5, a winding mechanism 6, a core-wrapping transmission mechanism 7, and a lead screw 8. The motor 15 is fixedly connected to the winding machine 1. The output end of the motor 15 passes through the winding machine 1 and is fixedly connected to the main shaft 5. The lead screw 8 is fixedly connected to the end of the main shaft 5 away from the winding machine 1. The core-wrapping transmission mechanism 7 is connected to the lead screw 8 through a lead screw nut 70. The output end of the cylinder 4 is fixedly connected to the cutting mechanism 3.

[0037] A drive gear 22 is fixedly connected to the outer side of the main shaft 5. A driven gear 23 is fixedly connected to one end of the winding mechanism 2 6. A gear ring 21 is fixedly connected to one side of the winding machine 1. A core-wrapping transmission mechanism 7 is provided with a core-wrapping clamp 71. A polygonal clamp 72 for accommodating the core is provided in the core-wrapping clamp 71. A winding clamp 65 fixedly connected to the core is provided in the winding mechanism 2 6. The gear ring 21 is meshed with the driven gear 23, and the drive gear 22 is meshed with the driven gear 23. The polygonal clamp 72 and the winding clamp 65 are arranged facing each other. Motor 15, Motor 2 16, Motor 3 17 and Motor 4 18 are all electrically connected to the controller 13.

[0038] On one hand, by placing the battery coating material on the coating roller 11 and the battery electrode on the electrode roller 12, and then driving the coating roller 11 and the electrode roller 12 to rotate, the battery electrode is pressed onto the battery coating by the guide roller 14. Then, by placing the carbon fiber battery core electrode into the core-wrapping transmission mechanism 7 and using the polygonal clamp 72 to clamp and fix the carbon fiber battery core electrode, and driving the main shaft 5 to rotate and drive the lead screw 8 fixed to it to rotate, so that the core-wrapping transmission mechanism 7 connected to the lead screw 8 moves along the axial direction of the lead screw 8 through the lead screw nut 70 until the carbon fiber battery core electrode approaches and is inserted into the winding mechanism 6, so that the winding clamp 65 fixes and holds the end of the carbon fiber battery core electrode away from the polygonal clamp 72.

[0039] On the other hand, by guiding the coating with battery electrode sheets onto the carbon fiber battery core electrode, the winding operation of the battery chip can be achieved by driving the polygonal clamp 72 to rotate, which in turn drives the carbon fiber battery core electrode to rotate, and the rotation of the carbon fiber battery core electrode drives the coating to rotate.

[0040] During this process, since the main shaft 5 is fixedly connected to the outside of the drive gear 22, one end of the winding mechanism 2 6 is fixedly connected to the driven gear 23, and one side of the winding machine 1 is fixedly connected to the gear ring 21, the gear ring 21 is meshed with the driven gear 23, and the drive gear 22 is meshed with the driven gear 23. Therefore, by driving the main shaft 5 to rotate and driving the drive gear 22 to rotate, the drive gear 22 can drive the driven gear 23 meshing with it to rotate around the main shaft 5. Before winding the carbon fiber battery core, the main shaft 5 needs to be rotated to adjust the winding mechanism 2 6 and the core-wrapping transmission mechanism 7 to the aligned position of the projection overlap, and the distance between the core-wrapping transmission mechanism 7 and the winding mechanism 2 6 needs to be adjusted. Then, the battery winding operation is achieved by rotating the polygonal clamp 72.

[0041] Furthermore, since the motor 15 is fixedly connected to the main shaft 5, the main shaft 5 is fixedly connected to the drive gear 22, and the lead screw 8 is fixedly connected to the main shaft 5, the purpose of rotating the winding mechanism 26 and adjusting the distance between the winding mechanism 26 and the core-wrap transmission mechanism 7 can be achieved through the motor 15, which effectively saves energy consumption in the winding operation, saves production costs, and enhances the market competitiveness of battery products.

[0042] Preferably, the second winding mechanism 6 includes a motor cylinder 61, a fixed plate 62, a gear B63, a rack B64, and a winding clamp 65. The motor cylinder 61 is fixedly connected to the driven gear 23. A third motor 17 is provided inside the motor cylinder 61. The outer shell of the third motor 17 is fixedly connected to the fixed plate 62. The output end of the third motor 17 passes through the fixed plate 62 and is fixedly connected to the gear B63. Two sets of racks B64 are provided, and both are meshed with the gears B63. One side of each set of racks B64 is fixedly connected to the winding clamp 65. The first motor 15, the second motor 16, the third motor 17, and the fourth motor 18 are all electrically connected to the controller 13.

[0043] The controller 13 drives the motor 17 to rotate the gear B63, which in turn drives the two racks B64 that mesh with it to move, thus moving the two racks B64 away from each other or closer to each other. The distance between the two sets of winding clamps 65 can be adjusted. The winding clamps 65 are easy and quick to adjust with high precision. The clamping offset of the winding clamps 65 is small, which effectively avoids the problem of the winding clamps 65 causing the carbon fiber battery core to shift during the clamping process.

[0044] During this process, the winding clamp 65 only needs to lightly clamp the outer side of the carbon fiber battery core electrode with the serration 66 at one end of the clamping end. It should not clamp the carbon fiber battery core electrode with force to avoid the problem of the multi-sided clamp 72 rotating and causing the carbon fiber battery core electrode to rotate and be stuck by the serration 66.

[0045] Preferably, both sides of the lead screw nut 70 are provided with core-filled clamps 71. A motor frame 78 is fixed to the outer side of the core-filled clamp 71. A second motor 16 is fixed to one side of the motor frame 78. The output end of the second motor 16 extends through the motor frame 78 and the core-filled clamp 71 into the interior of the core-filled clamp 71 and is fixed to a polygonal clamp 72. A spring plate 73 is fixed to the outer side of the polygonal clamp 72 by a spring 75. A locking rod 74 is fixed to one side of the spring plate 73, and the end of the locking rod 74 away from the spring plate 73 extends through the polygonal clamp 72 into the interior of the polygonal clamp 72. The first motor 15, the second motor 16, the third motor 17, and the fourth motor 18 are all electrically connected to the controller 13. The polygonal clamp 72 is set as a regular octagon, and the included angle between the extension lines of any two adjacent locking rods 74 is 45°.

[0046] By inserting the end of the carbon fiber battery core away from the winding mechanism 6 into the polygonal clamp 72, the carbon fiber battery core will squeeze the polygonal clamp 72, forcing the polygonal clamp 72 to move outward a short distance. When the carbon fiber battery core is completely inside the polygonal clamp 72, the polygonal clamp 72 will fix the carbon fiber battery core under the action of the spring plate 73 and the locking rod 74, thus ensuring the normal winding operation of the carbon fiber battery core. Then, the rotation of the motor 16 drives the polygonal clamp 72 to rotate, and the rotation of the polygonal clamp 72 drives the carbon fiber battery core to rotate normally.

[0047] During this process, the core-coated transmission mechanism 7 is convenient and quick to operate in clamping the carbon fiber battery core electrode. Since the polygonal clamp 72 is set as a regular octagon, the included angle between the extension lines of the two adjacent locking rods 74 is 45°. Therefore, the clamping stress of the polygonal clamp 72 on the carbon fiber battery core electrode is uniform, avoiding the phenomenon of carbon fiber battery core electrode displacement caused by uneven clamping stress. This further improves the stability of the carbon fiber battery core electrode clamping and ensures the quality of carbon fiber battery core electrode winding.

[0048] Preferably, the cutting mechanism 3 includes a cutting mechanism housing 31, a cutting blade holder 32, a cutting blade 33, a gear A34, and a rack A35. The cutting mechanism housing 31 is fixedly connected to the cylinder 4. A motor 4 18 is fixedly connected to the side of the cutting mechanism housing 31 away from the cylinder 4. The output end of the motor 4 18 passes through the cutting mechanism housing 31 and is fixedly connected to the gear A34. Two sets of racks A35 are provided, both of which are meshed with the gears A34. The rack A35 is fixedly connected to the cutting blade 33 through the cutting blade holder 32.

[0049] After the carbon fiber battery core is wound, the cutting mechanism 3 is moved by the driving cylinder 4 to bring the cutting blade 33 closer to the battery. At the same time, the driving motor 418 drives the gear A34 to rotate. The rotation of the gear A34 causes the rack A35, which is meshed with it, to move closer or further apart to adjust the relative distance between the two cutting blades 33. Then, the battery coating is cut by the cutting blade 33. The adjustment of the cutting blade 33 is convenient, quick and precise. The cutting position of the cutting blade 33 is accurate, which effectively ensures the quality of the cutting operation after the battery is wound.

[0050] After the battery is cut off, the main shaft 5 rotates to drive the winding mechanism 6 to rotate 180°, and then the other winding mechanism 6 and the core-wrapping transmission mechanism 7 are moved to the working position for battery winding, so that the battery winding operation can be continuously and uninterruptedly realized.

[0051] Preferably, a connecting arm 76 is provided on one side of the lead screw nut 70, and the end of the connecting arm 76 away from the lead screw nut 70 is fixedly connected to the core clamp 71. The lead screw nut 70 is movably connected to the connecting arm 76 through the rotation protection mechanism 9.

[0052] Preferably, the rotation protection mechanism 9 is provided with an outer ring 91 and an inner ring 92. The outer ring 91 is fixedly connected to the inner ring 92 by a fixing rod 94. The inner ring 92 is fixedly connected to the lead screw nut 70. A sliding shaft 77 is fixedly connected to one side of the connecting arm 76. A rotating cavity 93 is provided in the outer ring 91 and the inner ring 92. The sliding shaft 77 is movably connected to the rotating cavity 93.

[0053] Since one end of the carbon fiber battery core is fixedly clamped by the core-closing transmission mechanism 7 and the other end is fixedly clamped by the winding mechanism 6, when one core-closing transmission mechanism 7 is performing battery winding, the other core-closing transmission mechanism 7 can insert the carbon fiber battery core into it. Then, the position of the core-closing transmission mechanism 7 can be adjusted by rotating the winding mechanism 6. After one battery is wound, the other carbon fiber battery core is moved to the battery winding position, so that the battery winding operation can be continuously and uninterruptedly realized.

[0054] Preferably, the cutting blade holder 32 is provided in two sets, and the cutting blades 33 fixed to one side of the two sets of cutting blade holders 32 have overlapping projections.

[0055] The fact that the cutting blades 33 fixed to one side of the two sets of cutting blade holders 32 have overlapping projections can ensure that the battery is not deviated during the cutting operation, thus effectively ensuring the quality of battery cutting.

[0056] Preferably, an end cap 81 is fixedly connected to the end of the lead screw 8 away from the main shaft 5, and the diameter of the end cap 81 is larger than the diameter of the lead screw 8.

[0057] End cap 81 can prevent the lead screw nut 70 from moving to one end of the lead screw 8 and detaching from the lead screw 8 during the movement of the lead screw 8;

[0058] Preferably, the polygonal clamp 72 is configured as a regular octagon, and the included angle between the extension lines of any two adjacent locking rods 74 is 45°.

[0059] The polygonal clamp 72 provides uniform clamping stress for the carbon fiber battery core electrode, avoiding the displacement of the carbon fiber battery core electrode caused by uneven clamping stress. This further improves the stability of the carbon fiber battery core electrode clamping and ensures the quality of the carbon fiber battery core electrode winding.

[0060] Preferably, a sawtooth 66 is fixedly connected to one side of the winding clamp 65, and the first motor 15, the second motor 16, the third motor 17 and the fourth motor 18 are all electrically connected to the controller 13.
