Description

Technical Field

[0001] This invention belongs to the field of lithium battery winding, and particularly relates to a lithium battery winding process equipment. Background Technology

[0002] Lithium batteries are batteries that contain lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in their electrochemical system.

[0003] The winding process in lithium battery manufacturing includes operations such as mixing, coating, cold pressing, and cutting. In the mixing process, a mixer is used to uniformly mix the cathode or anode powder with other ingredients. The mixing process is as follows: 1. The high-speed rotation of the mixing head generates suction to draw in liquids and solids. 2. Centrifugal force causes the materials to move in a circular motion within the mixing head. 3. The materials are ejected from the mixing head. 4. The materials continue to move within the mixing tank and enter the next mixing cycle.

[0004] The mixer requires a long mixing time for powders and ingredients, needs to be repeated multiple times, and has a long mixing cycle, resulting in low efficiency.

[0005] This invention provides a highly efficient mixing device for mixing powders and ingredients, which eliminates the need for multiple cycles of mixing and can complete the thorough mixing of powders and ingredients in a single pass. Summary of the Invention

[0006] To address the aforementioned deficiencies in the prior art, this invention discloses a lithium battery winding process equipment, which is implemented using the following technical solution.

[0007] A lithium battery winding process equipment includes a ring cylinder, a ring sleeve B, a support, a base plate, a motor A, a circular tube, a mixing mechanism, a motor D, a feeding mechanism, and an electric push rod A. The annular area of ​​the ring cylinder, which is suspended by the support legs, is divided into several circumferentially evenly distributed fan-shaped storage spaces. Each fan-shaped space has a vertically sealed sliding fan-shaped base plate at its bottom, which changes its storage height and is synchronously driven by the motor A. A circular tube with the same central axis, driven by the motor B, rotates in the circular groove in the middle of the ring cylinder. The lower end of the circular tube is connected to a post-processing device with negative pressure. The upper end of the circular tube is equipped with a suction and mixing mechanism that, under the negative pressure of the post-processing device, sequentially sucks up material from each storage space above the annular area of ​​the cylinder and performs rapid and uniform non-circulating stirring and mixing of the sucked-up powder before it enters the circular tube. A ring sleeve B driven by a motor D is nested and rotated on the cylinder. A feeding mechanism driven by an electric push rod A slides vertically on the support fixed to the ring sleeve B, sequentially adding material from above the annular area of ​​the cylinder to each storage space.

[0008] As a further improvement to this technology, the annular area of ​​the ring cylinder is divided into several circumferentially evenly distributed fan-shaped storage spaces by several circumferentially evenly distributed partitions; each bottom plate is connected to a concentric ring plate below the ring cylinder by a connecting rod, and a concentric ring sleeve C nested in the circular tube is installed at the lower end of the ring plate; an internal threaded sleeve that rotates with the ring sleeve D on the support is nested and screwed on the ring sleeve C, and the concentric gear A on the internal threaded sleeve meshes with the gear B on the output shaft of the motor A.

[0009] As a further improvement to this technology, the circular tube rotates within the circular groove in the middle of the annular cylinder and is mounted in the ring sleeve A via a fixed rod; the lower end of the circular tube is sealed and rotated in conjunction with the suction pipe of the post-processing equipment; the gear C mounted on the circular tube meshes with the gear D mounted on the output shaft of the motor B; a gear ring is mounted on the ring sleeve B, and the gear ring meshes with the gear J on the output shaft of the motor D.

[0010] As a further improvement to this technology, the mixing mechanism includes a housing, a suction nozzle, a ring E, crossbars, blades A, a rotating shaft A, blades B, and a motor C. The circular cavity of the housing, mounted on the upper end of the circular tube, is connected to the circular tube. A ring E, driven by the motor C, is rotatably fitted in a circular groove at one end of the housing that communicates with the circular cavity. A rotating shaft A, driven by the same motor C, is rotatably fitted inside the ring E, and the rotation direction of the rotating shaft A is opposite to that of the ring E. Several sets of blades B are evenly spaced axially on the rotating shaft A, and each set of blades B has three blades B evenly distributed circumferentially. Several blades A are evenly spaced axially along the rotating shaft A on the three circumferentially distributed crossbars mounted on the ring E. The blades A on each crossbar and the blades B on the rotating shaft A are axially staggered. The lower end of the housing has a suction port tangent to the inner wall of the circular cavity of the housing, and a suction nozzle is installed at the suction port opposite to the annular area of ​​the ring cylinder.

[0011] As a further improvement to this technology, the rotating shaft A is rotatably engaged with the ring sleeve F installed in the circular groove at one end of the housing via a fixed rod; a gear E is installed on the ring sleeve E, and the gear E meshes with the gear F installed on the output shaft of the motor C; a gear G is installed on the rotating shaft A, and the gear G meshes with the gear H installed on the housing, and the gear H meshes with the gear I installed on the output shaft of the motor C.

[0012] As a further improvement to this technology, the feeding mechanism includes a slide block, an electric push rod A, a hopper, a baffle, an electric push rod B, a spiral blade, and a motor E. The hopper is mounted on the slide block, which slides vertically on the support under the drive of the electric push rod A. Inside the bottom of the hopper, a spiral blade reciprocates and rotates, under the drive of the motor E, to evenly fill the material in the hopper into the storage space within the annular area of ​​the ring cylinder through the discharge port at the bottom of the hopper. A baffle, driven by the electric push rod B, slides horizontally in the slot on the side wall of the hopper to open and close the hopper.

[0013] As a further improvement to this technology, a gear K is installed on the rotating shaft B where the spiral blade is located, and the gear K meshes with the gear L installed on the output shaft of the motor E.

[0014] Compared to traditional powder mixing equipment in lithium battery winding processes, this invention utilizes a suction mixing mechanism connected to a post-processing device with negative pressure to perform a single-pass, thorough mixing of the powder and ingredients filled in several spaces divided by partitions within the annular cylinder. This eliminates the need for reciprocating cyclic mixing of the powder and ingredients, shortening the mixing cycle and improving mixing efficiency. Furthermore, the blades A mounted on the crossbar and B on the rotating shaft A in the suction mixing mechanism rotate in opposite directions, creating turbulence within the housing to thoroughly mix the incoming powder and ingredients, further enhancing mixing efficiency and shortening the uniform mixing cycle. This invention features a simple structure and excellent performance. Attached Figure Description

[0024] The accompanying drawings are schematic diagrams illustrating embodiments of the present invention to facilitate understanding of the structural operating principle. Specific product structures and dimensions can be determined based on the usage environment and conventional technologies.

[0025] like Figure 1 , 2 As shown, it includes an annular cylinder 2, an annular sleeve B5, a support 6, a base plate 8, a motor A16, a circular tube 17, a motor B20, a suction and mixing mechanism 23, a motor D41, a feeding mechanism 42, and an electric push rod A45, wherein... Figure 3 , 4 As shown in Figure 5, the annular area of ​​the ring cylinder 2, suspended by the support leg 1, is divided into several circumferentially evenly distributed fan-shaped storage spaces. Each fan-shaped space has a vertically sealed sliding fan-shaped bottom plate 8 that changes its storage height and is synchronously driven by motor A16. A circular tube 17 with the same central axis, driven by motor B20, rotates within the circular groove in the middle of the ring cylinder 2. Figure 2 , 3 As shown in Figure 4, the lower end of the circular tube 17 is connected to the post-processing equipment 22 with negative pressure, and the upper end of the circular tube 17 is equipped with a suction and mixing mechanism 23, which, under the action of negative pressure of the post-processing equipment 22, sequentially sucks up material from above the annular area of ​​the ring cylinder 2 from each storage space and performs rapid and uniform non-circulating stirring and mixing of the sucked-up powder before it enters the circular tube 17; Figure 2 , 3 As shown in Figure 5, a ring sleeve B5 driven by a motor D41 is nested and rotated on the cylinder. A feeding mechanism 42, which is fixed to the support 6 of the ring sleeve B5 and is vertically slidable, is driven by an electric push rod A45 to add material to each storage space sequentially from above the annular area of ​​the cylinder 2.

[0026] like Figure 5 As shown, the annular region of the ring cylinder 2 is divided into several circumferentially evenly distributed fan-shaped storage spaces by several circumferentially evenly distributed partitions 3; as Figure 4 , 6 As shown, each base plate 8 is connected to a concentric ring plate 10 below the ring cylinder 2 via a connecting rod 9. A concentric ring sleeve C11 nested in the circular tube 17 is installed at the lower end of the ring plate 10. An internal threaded sleeve 12 is nested and screwed on the ring sleeve C11, which is rotatably engaged with the ring sleeve D13 on the support leg. The concentric gear A14 on the internal threaded sleeve 12 meshes with the gear B15 on the output shaft of the motor A16.

[0027] like Figure 3 , 5 As shown, the circular tube 17 rotates within the ring sleeve A4, which is installed via a fixed rod, within the circular groove in the middle of the annular cylinder 2; as Figure 4 As shown, the lower end of the circular tube 17 is in a sealed rotatable fit with the suction pipe 21 of the post-processing equipment 22; the gear C18 mounted on the circular tube 17 meshes with the gear D19 mounted on the output shaft of the motor B20; as shown Figure 3 As shown, a gear ring 39 is mounted on the ring sleeve B5, and the gear ring 39 meshes with the gear J40 on the output shaft of the motor D41.

[0028] like Figure 7 As shown, the mixing mechanism 23 includes a housing 24, a suction nozzle 26, a ring sleeve E27, a crossbar 28, a blade A29, a rotating shaft A30, a blade B32, and a motor C35, wherein... Figure 3 , 7 As shown, the cavity of the housing 24 installed on the upper end of the circular tube 17 is connected to the circular tube 17. A ring sleeve E27 driven by a motor C35 is rotatably fitted in a circular groove that communicates with the cavity at one end of the housing 24. A rotating shaft A30 driven by the same motor C35 is rotatably fitted in the ring sleeve E27, and the rotation direction of the rotating shaft A30 is opposite to the rotation direction of the ring sleeve E27. Several sets of blades B32 are evenly distributed axially on the rotating shaft A30, and each set of blades B32 has three blades B32 evenly distributed circumferentially. Several blades A29 are evenly installed along the axial direction of the rotating shaft A30 on the three circumferentially evenly distributed crossbars 28 installed on the ring sleeve E27. The blades A29 on each crossbar 28 and the blades B32 on the rotating shaft A30 are axially staggered. The lower end of the housing 24 has a suction port 25 tangent to the inner wall of the cavity of the housing 24. A suction nozzle 26 opposite to the annular area of ​​the ring cylinder 2 is installed at the suction port 25.

[0029] like Figure 7As shown, the rotating shaft A30 is rotatably engaged with the ring sleeve F31 installed in the circular groove at one end of the housing 24 via a fixed rod; a gear E33 is installed on the ring sleeve E27, and the gear E33 meshes with the gear F34 installed on the output shaft of the motor C35; a gear G36 is installed on the rotating shaft A30, and the gear G36 meshes with the gear H37 installed on the housing 24, and the gear H37 meshes with the gear I38 installed on the output shaft of the motor C35.

[0030] like Figure 8 As shown, the feeding mechanism 42 includes a slide 43, an electric push rod A45, a hopper 46, a baffle 48, an electric push rod B49, a spiral blade 50, and a motor E54, wherein... Figure 2 , 3 As shown in Figure 8, a hopper 46 is installed on a slide block 43 of the support 6, which slides vertically under the drive of an electric push rod A45. Inside the bottom of the hopper 46, there is a spiral blade 50 that reciprocates and rotates, which, under the drive of a motor E54, evenly fills the material in the hopper 46 into the storage space of the annular area of ​​the ring cylinder 2 through the discharge port 47 at the bottom of the hopper 46. A baffle 48 that controls the opening and closing of the hopper 46, driven by an electric push rod B49, slides horizontally in a slot on the side wall of the hopper 46.

[0031] like Figure 8 As shown, the shaft B51 where the spiral blade 50 is located is equipped with a gear K52, which meshes with a gear L53 installed on the output shaft of the motor E54.

[0032] like Figure 3 , 5 As shown in Figure 8, a trapezoidal guide block 44 is installed on the slide block 43, and the trapezoidal guide block 44 slides in the trapezoidal guide groove 7 on the support 6.

[0033] The working process of the present invention is as follows: In the initial state, the bottom plates 8 inside the ring cylinder 2 are all located at the bottom of the corresponding storage space, and the baffles 48 in the feeding mechanism 42 are in a closed state to the hopper 46.

[0034] When the present invention is used to uniformly mix materials in the stirring process of the lithium battery winding process, the hopper 46 of the feeding mechanism 42 is first filled with a quantitative amount of powdered material that can fill one storage space in the annular area of ​​the ring cylinder 2 through the filling device. The electric push rod A45 is then activated, and the electric push rod A45 drives the hopper 46 downward through the slide 43, so that the discharge port 47 at the bottom of the hopper 46 is flush with the upper end of the partition 3 in the ring cylinder 2. Then, the motors D41 and B20 are activated. The motor D41 drives the discharge port 47 at the bottom of the hopper 46 to be vertically aligned with any storage space separated by the partition 3 in the annular area of ​​the ring cylinder 2 through the gear J40, gear ring 39, ring sleeve B5, support 6, and slide 43.

[0035] At the same time, motor B20 drives the circular tube 17 to rotate through gears D19 and C18. The circular tube 17 drives the suction and mixing mechanism 23 to move above the annular area of ​​the ring cylinder 2. The rotational angular velocity of the suction and mixing mechanism 23 is equal to the rotational angular velocity of the feeding mechanism 42, so as to avoid interference between the feeding mechanism 42 and the suction and mixing mechanism 23 during the feeding process, and to enable the feeding mechanism 42 to fill all the storage space separated by the partition 3 in the ring cylinder 2.

[0036] When the discharge port 47 at the bottom of the hopper 46 in the feeding mechanism 42 is opposite to a storage space in the annular area of ​​the ring cylinder 2, the motors B20 and D41 stop running.

[0037] The electric actuator B49 and motor E54 are activated. The electric actuator B49 drives the baffle 48 to open the hopper 46, allowing a fixed amount of material to reach the bottom of the hopper 46. The motor E54 drives the spiral blade 50 to rotate reciprocally via gears L53 and K52 and the rotating shaft B51. The spiral blade 50 causes the powdery material falling to the bottom of the hopper 46 to fall evenly along the radial direction of the ring cylinder 2 into the storage space in the lower ring cylinder 2. When all the material in the hopper 46 has entered one of the storage spaces in the lower ring cylinder 2, the material in the storage space is just level with the upper end of the partition 3.

[0038] Then, the electric push rod B49 is activated to close the baffle 48 to the hopper 46. Motors D41 and B20 are then started. Motor B20, through gears D19 and C18, drives the circular tube 17 to rotate. The circular tube 17 drives the mixing mechanism 23 to move above the annular area of ​​the ring cylinder 2. Motor D41 drives the hopper 46 to rotate around the central axis of the ring cylinder 2 at a certain angle, so that the discharge port 47 of the hopper 46 reaches directly above the next storage space in the annular area of ​​the ring cylinder 2. At this time, the second material is loaded into the hopper 46.

[0039] Next, the electric push rod B49 and motor E54 are activated. The electric push rod B49 drives the baffle 48 to open the hopper 46, allowing the second type of metered material in the hopper 46 to reach the bottom. The motor E54 drives the spiral blade 50 to rotate reciprocally via gears L53 and K52 and the rotating shaft B51. The spiral blade 50 causes the second type of powdery material falling to the bottom of the hopper 46 to fall evenly along the radial direction of the ring cylinder 2 into the storage space in the lower ring cylinder 2. When all the second type of material in the hopper 46 has entered one of the storage spaces in the lower ring cylinder 2, the second type of material in the storage space is just flush with the upper end of the partition 3.

[0040] Then, the electric push rod B49 is activated to close the baffle 48 to the hopper 46. Motors D41 and B20 are then started. Motor B20, through gears D19 and C18, drives the circular tube 17 to rotate. The circular tube 17 drives the mixing mechanism 23 to move above the annular area of ​​the ring cylinder 2. Motor D41 drives the hopper 46 to rotate around the central axis of the ring cylinder 2 at a certain angle, so that the outlet 47 of the hopper 46 reaches directly above the next storage space in the annular area of ​​the ring cylinder 2. At this time, the third material is loaded into the hopper 46.

[0041] In this way, all kinds of powdery materials to be mixed are sequentially fed into all the storage spaces separated by the partition plate 3 within the annular area of ​​the ring cylinder 2 through the hopper 46 of the feeding mechanism 42.

[0042] When the storage space within the annular area of ​​the ring cylinder 2 is completely filled with powder, the electric push rod A45 is activated. The electric push rod A45 drives the hopper 46 in the feeding mechanism 42 to move vertically upward a certain distance, ensuring that the rotation of the mixing mechanism 23 driven by the circular tube 17 is not interfered with by the feeding mechanism 42.

[0043] Then, the post-processing equipment 22, motor C35, and motor B20 are started simultaneously. The negative pressure generated by the post-processing equipment 22 draws air outward from the housing 24 of the mixing mechanism 23 through the circular pipe 17, creating a negative pressure inside the housing 24. The suction port 25 at the lower end of the housing 24 draws powdery material from the storage space in the annular area of ​​the lower ring cylinder 2. Motor C35 drives the three crossbars 28 inside the circular cavity of the housing 24 to rotate around the rotating shaft A30 through gears F34, E33, and ring sleeve E27. The three crossbars 28 drive the blades A29 on them to rotate synchronously. At the same time, motor C35 drives the rotating shaft A30 to rotate through gears I38, H37, and G36. The rotation direction of the rotating shaft A30 is opposite to the rotation direction of the ring sleeve E27. The rotating shaft A30 drives the blades B32 on it to rotate synchronously. Blades A29 and B32, rotating in opposite directions, create turbulence within the circular cavity of the housing 24, ensuring thorough and uniform mixing of the powder entering the housing 24 from the suction port 25. The powder, mixed by blades A29 and B32, then travels through the circular pipe 17 to the post-processing equipment 22 under negative pressure. Simultaneously, motor B20, via a series of transmissions, drives the housing 24 to move around the central axis of the annular cylinder 2 above its annular region. This allows the suction port 25 of the housing 24 to sequentially draw in all the powder from the divided storage spaces within the annular region of the annular cylinder 2, performing thorough, rapid, and uniform mixing in a single pass. This eliminates the need for reciprocating cycles of mixing the same portion of powder material.

[0044] When the mixing mechanism 23 rotates exactly one revolution around the circular tube 17, the motor A16 is started. The motor A16 drives the internal threaded sleeve 12 to rotate through the gears B15 and A14. The internal threaded sleeve 12 drives all the bottom plates 8 to move upward through the ring sleeve C11 and the connecting rod 9, causing the powdery material in each storage space to rise and be flush with the upper end of the partition 3 again. This ensures that the suction port 25 at the lower end of the housing 24 in the mixing mechanism 23 can effectively suck up the powdery material in all the storage spaces separated by the partition 3.

[0045] As the mixing mechanism 23 continues to rotate around the circular tube 17, the mixing mechanism 23 sequentially and repeatedly draws powder from all the storage spaces separated by the partition 3 in the annular area of ​​the ring cylinder 2 and mixes them thoroughly. When the mixing mechanism 23 rotates once, the motor A16 is started to drive all the bottom plates 8 to lift the material in each storage space whose height has been significantly reduced, so that the material is flush with the top of the partition 3, ensuring that the mixing mechanism 23 effectively draws the material in each storage space.

[0046] Once all the material in the storage space separated by the partition plate 3 within the annular area of ​​the ring cylinder 2 has been completely sucked away, start the motor A16 to drive all the bottom plates 8 to reset.

[0047] In summary, the beneficial effects of this invention are as follows: This invention, through a suction mixing mechanism 23 connected to a post-processing device 22 with negative pressure function, performs a single-pass thorough mixing of the powder and ingredients filled in the spaces divided by the partition 3 within the annular cylinder 2. This eliminates the need for reciprocating cyclic mixing of the powder and ingredients, shortening the mixing cycle and improving mixing efficiency. Furthermore, the blades A29 mounted on the crossbar 28 and B32 on the rotating shaft A30 in the suction mixing mechanism 23 rotate in opposite directions, creating turbulent flow within the housing 24 to thoroughly mix the entering powder, thereby improving the mixing efficiency of the powder and ingredients and shortening the uniform mixing cycle.
