Description

Technical Field

[0001] This utility model belongs to the field of battery core electrode separation technology, specifically relating to a battery core electrode separation device. Background Technology

[0002] With the widespread application of new energy technologies, lithium batteries, with their advantages of high energy density, high rate performance, long cycle life, and high operating voltage, have become a widely used new type of energy storage battery in electronic devices, new energy vehicles, and other fields. Especially in the new energy vehicle sector, as major automakers accelerate their new energy transformation, the installed capacity of power batteries will increase significantly in the future. The ever-increasing global demand for lithium battery materials has led to a surge in the prices of key battery materials, pushing up manufacturing costs for lithium battery manufacturers and posing a serious challenge to the sustainable development of my country's new energy vehicle industry. Meanwhile, as electric vehicles are used for many years, the battery capacity gradually decreases. When the battery capacity decays to 80% of its initial capacity, the electric vehicle battery needs to be retired and replaced; retired batteries are no longer used as power batteries. Retired lithium batteries contain high-value elements, such as copper, aluminum, lithium, nickel, and cobalt in the positive and negative electrode materials. Direct disposal would not only result in a huge waste of resources but also cause serious environmental pollution.

[0003] Existing waste lithium battery recycling methods mostly employ physical processing, which involves discharging the lithium batteries and then feeding them into a crushing and separation device for crushing and screening. Lithium battery cells consist of positive electrode sheets, separators, and negative electrode sheets. During the crushing process, all materials are mixed together, requiring manual or screening machine sorting and picking out later. Furthermore, the fragmentation of materials after the battery pack is crushed affects the efficiency of the recycling process and the effectiveness of material sorting and recycling. Therefore, those skilled in the art have provided a battery core electrode sheet separation device to solve the problems mentioned in the background art. Utility Model Content

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 , Figure 2 As shown, a battery core electrode separation device includes a lower housing 55. Inside the lower housing 55 are two identical positive electrode feeding lines 51 and negative electrode and separator feeding lines 52. The top of the lower housing 55 is fixedly connected to an upper housing 56. The top of the upper housing 56 is fixedly connected to a warning light 57. Inside the upper housing 56 are a positioning component 1, a first strong blowing knife 2, a transfer mechanism 3, a cell lifting mechanism 4, and a hot melt film mechanism 5. Inside the upper housing 56 are a lifting component 21, a double top 22, and a baffle 23.

[0026] like Figure 3 , Figure 4 and Figure 5As shown, the positioning component 1 includes a positioning edge 6 fixedly connected to the bottom of the inner wall of the upper housing 56. A positioning cylinder 7 is provided on the rear side of the top of the positioning edge 6. The main function of the positioning component 1 is to assist in positioning the battery cell position during the operation of the hot melt film mechanism 5, and to prevent the battery cell from moving. The first strong air knife 2 includes a first air knife angle adjustment component 9 fixedly connected to both sides of the upper front end of the positioning edge 6. An air knife 8 is provided between the two first air knife angle adjustment components 9. The main function of the first strong air knife 2 is to blow and flip the melted diaphragm to the diaphragm clamping position on the platform. The transfer mechanism 3 includes a positioning edge 6 fixedly connected to the bottom of the inner wall of the upper housing 56. The first slider rail 12 is fixedly connected to the end of the first slider rail 12. A first cylinder 10 is provided at the bottom of the movable end of the first slider rail 12. A magnetic position switch 11 is fixedly provided on the side wall of the fixed end of the first cylinder 10. The main function of the transfer mechanism 3 is to transport the battery cell to the battery cell flipping position and the diaphragm clamping position. The battery cell lifting mechanism 4 includes a right-angle reducer 14 fixedly connected to the bottom of the movable end of the first slider rail 12. A drive motor 13 is fixedly connected to the input end of the right-angle reducer 14. A lifting screw 15 is fixedly connected to the output end of the right-angle reducer 14. Four first linear bearings 1 are provided at the top of the movable end of the first slider rail 12. 6. The main function of the battery cell lifting mechanism 4 is to adjust the height of the battery cell. The hot melt film mechanism 5 includes a second linear bearing 19 located at the middle of the top of the positioning edge 6. A lifting cylinder 17 is fixedly connected to the middle of the top of the second linear bearing 19. A hot cutting blade 18 is fixedly connected to the output end of the lifting cylinder 17. A distance sensor 20 is fixedly connected to one side of the top of the second linear bearing 19. The front end of the positioning cylinder 7 is fixedly connected to the top of the second linear bearing 19. The main function of the hot melt film mechanism 5 is to hot melt the battery cell separator. The battery cell is transported to the loading position by the robot arm. The distance sensor 20 detects the position of the battery cell and outputs a signal to the battery cell lifting mechanism. The lowering mechanism 4, driven by the motor 13, drives the lifting screw 15 to raise the battery cell to the set position. The lifting cylinder 17 of the hot melt film mechanism 5 drives the hot cutting blade 18 to be pushed out to the upper surface of the battery cell and stay for a set time. After the double-layer separator of the battery cell is melted by the high temperature of the hot cutting blade 18, the lifting cylinder 17 drives the hot cutting blade 18 to retract. At this time, the strong blowing knife 8 is opened, and the high-speed air curtain blows the melted separator to the separator clamping position. Then the battery cell lifting mechanism 4 drives the motor 13 to run, raising the battery cell to the battery cell centering position height. At the same time, the transfer mechanism 3 moves the battery cell to the battery cell thickness centering and separator clamping position.

[0027] like Figure 6As shown, the lifting assembly 21 includes three second slider rails 26 fixedly connected to the middle of the bottom end of the inner wall of the upper housing 56. One of the second slider rails 26 and the other two are respectively fixedly connected to the top of a second cylinder 24. The three second slider rails 26 form one group and the other two groups. Two second cylinders 24 are respectively installed on these two groups. Magnetic switches 25 are fixedly connected to the side walls of the fixed ends of the two second cylinders 24. The function of the lifting assembly 21 is to drive the double-center 22 and the linear module 27 to rise and fall. The battery cell, with double centers 22, includes a stop 23 fixedly connected to the movable end of the first linear bearing 16 on one side. The movable ends of the other two second slider rails 26 are slidably connected to linear modules 27 fixedly connected to the output ends of the second cylinders 24. The movable ends of the linear modules 27 are slidably connected to the stop 23. The main function of the double centers 22 is to center and hold the battery cell in place under the action of the lifting assembly 21 and the linear modules 27, acting as a pivot for cell rotation. A movable center 29 is fixedly connected to one end of the stop 23 at the front end of the linear modules 27. The upper housing 56 has a fixed top 28 at the end and a baffle 23, the main function of which is to prevent the electrode from deviating laterally during the flipping and separation of the battery cell electrode, which would cause the electrode to break. The bottom of the inner wall of the upper housing 56 is fixedly connected to a double slide rail linear module 30. The movable end of the double slide rail linear module 30 is fixedly connected to two gripper cylinders 31. The diaphragm gripping mechanism is mainly used to grip the diaphragm and separate the electrode. The battery cell is transported to the battery cell thickness centering position by the transfer mechanism 3. The double top 22 is raised from the battery cell flipping position to the centering position under the action of the cylinder of the lifting component 21. The linear module 27 drives... The moving tip 29 is inserted into the center of the cell thickness. At the same time, the double slide rail linear module 30 drives the open gripper cylinder 31 to move to the diaphragm gripping position. The gripper cylinder 31 closes and clamps the diaphragm. Then the transfer mechanism 3 returns to the loading position, so that the cell is suspended below. Then the double slide rail linear module 30 drives the gripper cylinder 31 to return to the initial position. At the same time, because the diaphragm is stretched by the gripper cylinder 31, the cell is passively rotated around the double tip 22. Finally, the lifting component 21 drives the cell on the double tip 22 to descend to the cell rotation position.

[0028] like Figure 7As shown, the upper pressure roller assembly 32 includes a mounting frame 58 fixedly connected to the bottom end of the inner wall of the upper housing 56. A third linear bearing 36 is fixedly connected to the top end of the mounting frame 58, and a brush 45 is fixedly connected to the middle of the top end of the third linear bearing 36. The output end of the third cylinder 35 passes through the mounting frame 58 and is fixedly connected to the upper pressure roller 34. The main function of the upper pressure roller assembly 32 is to press the diaphragm and the negative electrode sheet, push against the lower roller assembly 33, and provide static friction. The lower roller assembly 33 includes a support frame 59 fixedly connected to the bottom end of the inner wall of the upper housing 56, and the support frame 59 is located at the bottom end of the mounting frame 58. An elastic passive roller 39 is rotatably connected to the front side of the inner wall of the support frame 59. A first motor 38 is fixedly connected to one side of the support frame 59. The output end of the machine 38 is fixedly connected to one side of the support frame 59 with an active roller 37. The main function of the lower roller assembly 33 is to provide power for the separation of the electrode sheets. Under the action of the third cylinder 35, the upper pressure roller 34 extends downward to the position between the active roller 37 and the elastic passive roller 39, so that the upper pressure roller 34 presses the active roller 37 and the elastic passive roller 39 at the same time. After the first motor 38 rotates, the active roller 37, the upper pressure roller 34, and the elastic passive roller 39 roll and rotate, giving the electrode sheets a continuous and appropriate pulling force, so that the battery cell continuously flips and the electrode sheet diaphragm continuously separates. At the same time, when the roller pressing and distributing mechanism is in operation, the gripper cylinder 31 opens and releases the diaphragm, so that the negative electrode sheet between the diaphragms falls onto the conveyor belt below.

[0029] like Figure 8As shown, the upper reversing brush assembly 40 and the lower reversing brush assembly 41 have the same structure. The upper reversing brush assembly 40 is located at the rear end of the upper pressure roller assembly 32, and the lower reversing brush assembly 41 is located at the rear end of the support frame 59. The upper reversing brush assembly 40 includes a brush 45. A second motor 44 is provided on one side of the brush 45. A synchronous belt and synchronous pulley assembly 46 is fixedly provided at the output end of the second motor 44. The output end of the synchronous belt and synchronous pulley assembly 46 is fixedly connected to one end of the brush 45. The main function of the upper reversing brush assembly 40 and the lower reversing brush assembly 41 is to reverse the contact of the upper and lower brushes with the electrode to scrape the electrode and the diaphragm apart, thereby achieving the purpose of separating the electrode and the diaphragm. The electrode blowing air knife assembly 42 includes a second air knife angle adjustment group fixedly connected to both sides of the rear end of the upper pressure roller assembly 32. The first component, 48, has a second strong air-blowing knife 47 fixedly connected between two second air-knife angle adjustment components 48. The main function of the air-knife assembly 42 is to blow away the positive electrode sheet with broken electrolyte on the electrode sheet. The brush cylinder assembly 43 includes a fourth linear bearing 50 fixedly connected to both sides of the top of the mounting frame 58. A single-axis cylinder 49 is fixedly connected to the top of the two fourth linear bearings 50. The output end of the single-axis cylinder 49 passes through the top of the mounting frame 58 and is fixedly connected to the top of the upper reversing brush assembly 40. The main function of the brush cylinder assembly 43 is to drive the upper reversing brush assembly 40 to rise and fall, achieving the purpose of the avoidance gripper cylinder 31. The upper reversing brush 45 and the upper pressure roller 34 extend downwards simultaneously to ensure that the positive electrode sheet does not flow into the conveyor line where the negative electrode and the diaphragm are located. When the upper and lower brushes contact the surface of the electrode sheet, the brush 45 performs a reverse motion under the rotation of the motor, brushing off the electrolyte on the diaphragm and the positive electrode sheet that has not fallen to the conveyor line due to gravity.

[0030] like Figure 9 As shown, the positive electrode sheet feeding line 51 and the negative electrode sheet and diaphragm feeding line 52 include a flat belt 53 fixedly connected to the middle of the inner wall of the lower housing 55. A third motor 54 is provided on one side of the flat belt 53. The positive electrode sheet feeding line 51 and the negative electrode sheet and diaphragm feeding line 52 mainly transport the separated electrode sheets and diaphragms to the next process for processing.

[0031] It should be noted that in this battery core electrode separation equipment, the battery cell is transported to the loading position by a robotic arm during use. The distance sensor 20 detects the position of the battery cell and outputs a signal to the battery cell lifting mechanism 4. The drive motor 13 drives the lifting screw 15 to lift the battery cell to the set position. The lifting cylinder 17 of the hot melt film mechanism 5 drives the hot cutting blade 18 to push out to the upper surface of the battery cell and stay for a set time. After the double-layer separator of the battery cell is melted by the high temperature of the hot cutting blade 18, the lifting cylinder 17 drives the hot cutting blade 18 to retract. At this time, the strong blowing knife 8 is opened, and the high-speed air curtain blows the melted separator to the separator clamping position. Then, the battery cell lifting mechanism 4 drives the drive motor 13 to run, lifting the battery cell to the battery cell centering position height. At the same time, the transfer mechanism 3 drives the battery cell to the battery cell thickness centering and separator clamping position.

[0032] The battery cell is transported to the battery cell thickness centering position by the transfer mechanism 3. The double top 22 is raised from the battery cell flipping position to the centering position under the action of the cylinder of the lifting component 21. The linear module 27 drives the moving top 29 to push into the center of the battery cell thickness. At the same time, the double slide rail linear module 30 drives the open gripper cylinder 31 to move to the diaphragm gripping position. The gripper cylinder 31 closes and clamps the diaphragm. Then the transfer mechanism 3 returns to the loading position, so that the battery cell is suspended below. Then the double slide rail linear module 30 drives the gripper cylinder 31 of the gripper diaphragm to return to the initial position. At the same time, because the diaphragm is stretched by the gripper cylinder 31, the battery cell is passively flipped around the double top 22. Finally, the lifting component 21 drives the battery cell on the double top 22 to descend to the battery cell flipping position.

[0033] Under the action of the third cylinder 35, the upper pressure roller 34 extends downward to the position between the active roller 37 and the elastic passive roller 39, so that the upper pressure roller 34 presses the active roller 37 and the elastic passive roller 39 at the same time. After the first motor 38 rotates, the active roller 37, the upper pressure roller 34, and the elastic passive roller 39 roll and rotate, giving the electrode a continuous and appropriate pulling force, so that the battery cell keeps turning over and the electrode diaphragm keeps separating. At the same time, when the roller pressing and distributing mechanism is in operation, the gripper cylinder 31 opens and releases the diaphragm, so that the negative electrode between the diaphragms falls onto the conveyor belt below.

[0034] The upper reversing brush 45 and the upper pressure roller 34 extend downwards simultaneously to ensure that the positive electrode sheet does not flow into the conveyor line where the negative electrode and the diaphragm are located. When the upper and lower brushes come into contact with the electrode sheet surface, the brush 45 performs a reverse motion under the rotation of the motor, brushing off the electrolyte on the diaphragm and the positive electrode sheet that has not fallen onto the conveyor line due to gravity.

[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
