Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, specifically to a battery production device for adjusting the ratio of silicon to graphite. Background Technology

[0002] Lithium-ion batteries are among the most commercially available batteries. Their main materials include positive and negative electrode materials, electrolytes, and separators. Positive electrode materials mainly include lithium cobalt oxide, ternary materials, and lithium iron phosphate, while negative electrode materials mainly include graphite and silicon. The electrolyte is usually an organic solvent or a solid material.

[0003] In the production of lithium-ion batteries, the ratio of silicon to graphite in the silicon anode material is a key parameter that directly affects the performance of the lithium-ion battery. Increasing the proportion of silicon leads to higher specific capacity and specific energy. Silicon has a theoretical specific capacity of 4200 mAh / g, which is ten times that of graphite, making it an ideal choice for improving battery energy density. However, silicon has a high degree of expansion, and excessive silicon content may damage the battery structure during charging and discharging. Graphite also plays an important role in the silicon anode material. Graphite has good stability and high conductivity, which can effectively improve the durability and stability of the battery. However, graphite has relatively low specific capacity and specific energy. Therefore, the ratio of silicon to graphite is particularly important. In the production of lithium-ion batteries, the mixing of lithium battery cell slurry is a crucial step in the entire production process. However, it is difficult to automatically control the ratio of silicon to graphite each time silicon and graphite are mixed. It is necessary to measure the mass of silicon and graphite in advance before mixing them, which affects the efficiency of battery production. Summary of the Invention

[0006] An automatic material control device, installed on a sealed tank, is used to control the ratio of silicon and graphite added.

[0007] The automatic material control device includes two sets of rotating parts, which are rotatably connected to the bottom of a sealed tank. Two sets of hoppers are fixed inside the sealed tank.

A drive motor is installed at the top of the support frame, and threaded rods are fixed to the output shafts at both ends of the drive motor. A sealing element is connected to the bottom of the limiter via a connecting shaft, and a pressure sensor is installed on the top of the sealing element.

[0008] As a preferred embodiment of the present invention, a baffle is installed on the top of the conveying cylinder, a connector is fixed on the top of the baffle, a limiting circular plate is sleeved on the inner wall of the connector, a first movable member is fixed in the middle of the limiting circular plate, a first spring is sleeved on the outer surface of the first movable member, the bottom end of the first movable member passes through a second movable member and is fixed with a pressing member, a long rod is installed on the top of the inner cavity of the hopper, a number of first slots are opened on the top of the conveying cylinder, an arc plate is hinged inside the first slot by a torsion spring, a connecting frame is fixed on the top of each arc plate, and two sets of sealing caps are provided on the outside of the sealed tank.

[0009] As a preferred embodiment of the present invention, the limiting member is a right-angled triangle, the second movable member is a cone, the inclined surface of the limiting member is in extrusive contact with the outer surface of the second movable member, and when the limiting member extrudes the second movable member, it can restrict the downward movement of the second movable member.

[0010] As a preferred embodiment of the present invention, the threaded rod is threadedly connected to the movable plate, the thread directions of the two sets of threaded rods are opposite, the movable plate is slidably connected to the support frame, and the support frame and the bottom of the movable plate are in extrusion contact.

[0011] As a preferred embodiment of the present invention, the second spring is elastically supported between the rotating member and the second movable member, the pressure sensor is sleeved on the bottom end of the conveying cylinder, the sealing member is sleeved on the bottom end of the fixed tube, and the top surface of the sealing member is in contact with the bottom end of the conveying cylinder.

[0012] As a preferred embodiment of the present invention, the first spring is elastically supported between the baffle and the limiting circular plate, and the part of the feed cylinder that passes through the rotating member protrudes outward. When the feed cylinder moves downward, the protruding part can be blocked by the rotating member.

[0013] As a preferred embodiment of the present invention, the connecting member is sleeved on the outer surface of the long rod, the first movable member is sleeved on the inner wall of the long rod, the first movable member is in pressing contact with the long rod, and the tops of the baffle and the connecting member are both conical.

[0014] As a preferred embodiment of the present invention, the extruder is conical, and the bottom end of the extruder is in extrusion contact with the connecting frame. In the initial state, the arc-shaped plate is embedded in the inner wall of the first slot. When the extruder extrudes the connecting frame, the second movable member can rotate along the inner wall of the first slot.

[0015] As a preferred embodiment of the present invention, the stirring paddle is controlled to rotate by the output shaft of the control machine, the stirring tank is controlled to rise and fall by the control machine, and when the control machine is raised and lowered, its top can be sealed by the sealing tank. The two sets of hoppers are respectively connected to two sets of conveying cylinders, and the two sets of hoppers are respectively filled with silicon or graphite. When the sealing cover is opened, the hoppers can be filled with raw materials.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. This invention uses two sets of hoppers to feed silicon and graphite raw materials into two sets of feeding cylinders respectively. A pressure sensor is used to weigh the raw materials that have been fed in, and the feed rate of the two sets of feeding cylinders is controlled according to the set specific gravity. At the same time, the threaded rod controls the two sets of long rods to move in opposite directions, changing the position of the limiting part pressing the second movable part. Under the elastic force of the second spring, the second movable part will move downward, thereby causing the sealing part and pressure sensor to separate from the feeding cylinder through the connecting shaft. At this time, the raw materials inside the feeding cylinder can be discharged into the interior of the mixing tank, which facilitates the automatic control of the silicon to graphite ratio.

[0018] Second, the present invention uses the cooperation between the extrusion component and the connecting frame to drive the arc plate to rotate along the inner side of the first groove, so that several sets of arc plates can be unfolded at the same time. At the same time, by controlling the rotation of the transmission shaft, the fixed tube will be driven to rotate through the cooperation between the transmission belt and the rotating wheel. At this time, through the cooperation between the rotating component and the feeding cylinder, the feeding cylinder will rotate synchronously. When the feeding cylinder rotates, it will drive the arc plate to dig out the raw materials inside the hopper, thereby automatically feeding the material.

[0019] Third, this invention adds silicon and graphite to the inside of the two sets of hoppers separately through a sealing cover, without the need to measure the mass of silicon and graphite in advance. At the same time, the raw materials inside the hoppers are discharged from the bottom of the fixed pipe by controlling the conveying cylinder, and the discharge amount of the raw materials is automatically controlled. In addition, there is no need to add pipes to the outside. By controlling the position of the raw materials to be discharged from the bottom of the fixed pipe, the space occupied during feeding can be reduced.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-9 As shown, the present invention provides a battery production device for adjusting the ratio of silicon to graphite, including a control platform 1, a sealed tank 2 disposed at the top of the inner wall of the control platform 1, a stirring tank 3 disposed at the bottom of the inner wall of the control platform 1, and a stirring paddle 6 disposed at the bottom of the sealed tank 2, and further comprising:

[0033] An automatic material control device, installed on the sealed tank 2, is used to control the ratio of silicon and graphite added.

[0034] The automatic material control device includes two sets of rotating parts 7, which are rotatably connected to the bottom of the sealed tank 2. Two sets of hoppers 16 are fixed inside the sealed tank 2. A stirring rod 8 is fixed to the bottom of the rotating part 7, and a fixed pipe 5 is fixed to the top of the rotating part 7. A rotating wheel 9 is fixed to the outer wall of the top of the fixed pipe 5. A drive shaft 11 is fixed to the output end of the control unit 1. A drive belt 12 connects the drive shaft 11 and the rotating wheel 9. A conveying cylinder 13 passes through the middle of the rotating part 7, and the conveying cylinder 13 is slidably connected to the long rod 17. A second movable part 24 is sleeved on the outer surface of the conveying cylinder 13. A second spring 25 is fitted on the outer surface of the material cylinder 13. Two sets of second slots 26 are opened on the top of the rotating part 7. A movable plate 27 is slidably connected inside the second slot 26. A limiter 28 is fixed at the bottom end of the movable plate 27. A pneumatic cylinder 29 is installed at the top of the inner cavity of the rotating part 7. A support frame 30 is connected to the top of the pneumatic cylinder 29. A drive motor 31 is installed at the top of the support frame 30. Threaded rods 32 are fixed to the output shafts at both ends of the drive motor 31. A sealing member 34 is connected to the bottom end of the limiter 28 through a connecting shaft 33. A pressure sensor 10 is installed on the top of the sealing member 34.

[0035] The operation of the pneumatic cylinder 29 controls the support frame 30 to drive the movable plate 27 to rise, thereby driving the second movable member 24 to move upward through the limiting member 28. At this time, the second movable member 24 will pull the sealing member 34 through the connecting shaft 33 and drive the conveying cylinder 13 to move upward, thus driving the conveying cylinder 13 into the hopper 16. Silicon and graphite raw materials are respectively put into the two sets of conveying cylinders 13 through the two sets of hoppers 16. The pressure sensor 10 is used to weigh the put-in raw materials and control the feed amount of the two sets of conveying cylinders 13 according to the set specific gravity. The operation of the threaded rod 32 can drive the two sets of long rods 17 to move in opposite directions, thus changing the position of the limiting member 28 pressing the second movable member 24. Under the elastic force of the second spring 25, the second movable member 24 will be driven to move downward, thereby driving the sealing member 34 and the pressure sensor 10 to separate from the conveying cylinder 13 through the connecting shaft 33. At this time, the raw materials inside the conveying cylinder 13 can be discharged into the mixing tank 3, which facilitates the automatic control of the ratio of silicon to graphite.

[0036] like Figure 4 , 5 As shown, a baffle 14 is installed on the top of the conveying cylinder 13, and a connector 15 is fixed on the top of the baffle 14. A limiting circular plate 18 is sleeved on the inner wall of the connector 15. A first movable member 19 is fixed in the middle of the limiting circular plate 18. A first spring 20 is sleeved on the outer surface of the first movable member 19. The bottom end of the first movable member 19 passes through the second movable member 24 and is fixed with an extrusion member 21. A long rod 17 is installed on the top of the inner cavity of the hopper 16. Several sets of first slots 22 are opened on the top of the conveying cylinder 13. An arc plate 23 is hinged inside the first slot 22 by a torsion spring. A connecting frame 35 is fixed on the top of each arc plate 23. Two sets of sealing caps 4 are provided on the outside of the sealed tank 2.

[0037] By controlling the extension of the conveying cylinder 13 into the hopper 16, during the upward movement of the conveying cylinder 13, the baffle 14 will push the first spring 20 to cause the limiting circular plate 18 to drive the first movable member 19 to move upward until the first movable member 19 is blocked by the long rod 17. When the first movable member 19 and the long rod 17 are squeezed, the baffle 14 will slide upward along the outer surface of the first movable member 19, thereby causing the extrusion member 21 to squeeze with the connecting frame 35. At this time, the arc plate 23 will rotate along the inner side of the first slot 22, causing several sets of arc plates 23 to unfold simultaneously. At the same time, by controlling the rotation of the transmission shaft 11, the fixed tube 5 will be driven to rotate through the cooperation between the transmission belt 12 and the rotating wheel 9. At this time, through the cooperation between the rotating member 7 and the conveying cylinder 13, the conveying cylinder 13 will rotate synchronously. When the conveying cylinder 13 rotates, it will drive the arc plate 23 to dig out the raw material inside the hopper 16, allowing the raw material to quickly enter the interior of the conveying cylinder 13 through the first slot 22, thereby quickly feeding the material.

[0038] like Figure 3 As shown, the limiting member 28 is a right-angled triangle, and the second movable member 24 is a cone. The inclined surface of the limiting member 28 is in contact with the outer surface of the second movable member 24, and when the limiting member 28 presses against the second movable member 24, it can restrict the second movable member 24 from moving downward.

[0039] The cooperation between the limiting member 28 and the second movable member 24 restricts the downward movement of the second movable member 24. At the same time, the cooperation between the limiting member 28 and the second movable member 24 applies a pulling force to the second movable member 24 when the limiting member 28 moves upward, thereby driving the sealing member 34 to move upward through the connecting shaft 33, which facilitates the control of the conveying cylinder 13 to move upward.

[0040] like Figure 9 As shown, the threaded rod 32 is threadedly connected to the movable plate 27, and the threads of the two sets of threaded rods 32 are opposite in direction. The movable plate 27 is slidably connected to the support frame 30, and the support frame 30 is in contact with the bottom of the movable plate 27 by compression.

[0041] Through the cooperation between the threaded rod 32 and the movable plate 27, when the threaded rod 32 rotates, it can drive the movable plate 27 to slide along the outer surface of the support frame 30, thereby changing the distance between the limiting member 28 and the second movable member 24. At this time, the second movable member 24 will slide down, and then drive the sealing member 34 and the pressure sensor 10 to separate from the conveying cylinder 13 through the connecting shaft 33, so as to facilitate the discharge of the raw material inside the conveying cylinder 13. Furthermore, through the rotation of the conveying cylinder 13, the centrifugal force is used to fully discharge the raw material.

[0042] like Figure 2 , 3 As shown, the second spring 25 is elastically supported between the rotating part 7 and the second movable part 24, the pressure sensor 10 is sleeved on the bottom end of the conveying cylinder 13, the sealing part 34 is sleeved on the bottom end of the fixed tube 5, and the top surface of the sealing part 34 is in contact with the bottom end of the conveying cylinder 13.

[0043] The design of the second spring 25 enables the second movable member 24 to have good elastic reset performance. Since the second spring 25 is in a compressed state, it will apply an elastic force to the second movable member 24, thereby driving the connecting shaft 33 and the sealing member 34 to move downward. Through the cooperation between the sealing member 34 and the feeding cylinder 13, the bottom of the feeding cylinder 13 and the fixed tube 5 can be sealed, thereby preventing the raw materials from entering the interior of the fixed tube 5 when the battery raw materials are stirred.

[0044] like Figure 3 , 4As shown, the first spring 20 is elastically supported between the baffle 14 and the limiting circular plate 18. The part of the feed cylinder 13 that passes through the rotating member 7 protrudes outward. When the feed cylinder 13 moves downward, the protruding part can be blocked by the rotating member 7.

[0045] The design of the first spring 20 enables the limiting circular plate 18 to have good elastic reset performance, thereby supporting the limiting circular plate 18 through the first spring 20, thus preventing the first moving part 19 from falling downward under the influence of gravity; the design of the conveying cylinder 13, since the part of the conveying cylinder 13 that passes through the rotating part 7 protrudes outward, restricts the downward movement of the conveying cylinder 13, preventing the conveying cylinder 13 from moving downward under the influence of gravity when the sealing part 34 moves downward, thereby allowing the sealing part 34 and the pressure sensor 10 to separate from the conveying cylinder 13, facilitating the discharge of materials.

[0046] like Figure 4 As shown, the connector 15 is sleeved on the outer surface of the long rod 17, the first movable part 19 is sleeved on the inner wall of the long rod 17, the first movable part 19 is in contact with the long rod 17 by compression, and the tops of the baffle 14 and the connector 15 are both conical.

[0047] The cooperation between the connector 15 and the long rod 17 can prevent the raw materials inside the hopper 16 from entering the interior of the connector 15 and affecting the movement space of the connector 15. In addition, the tops of the baffle 14 and the connector 15 are both conical, which can reduce the resistance when the baffle 14 and the connector 15 move upward, thereby reducing the energy consumption of the pneumatic cylinder 29.

[0048] like Figure 4 , 5 As shown, the extruder 21 is conical, and the bottom end of the extruder 21 is in contact with the connecting frame 35. In the initial state, the arc plate 23 is embedded in the inner wall of the first slot 22. When the extruder 21 extrudes the connecting frame 35, the second movable member 24 can rotate along the inner wall of the first slot 22.

[0049] Through the cooperation between the extruder 21 and the connecting frame 35, when the extruder 21 extrudes the connecting frame 35, the connecting frame 35 will push the arc plate 23, causing the arc plate 23 to rotate along the inner side of the first slot 22, thus opening the first slot 22, and using the arc plate 23 to dig out the raw material into the inside of the conveying cylinder 13.

[0050] As shown in 1 and 2, the stirring paddle 6 is controlled to rotate by the output shaft of the control machine 1, and the stirring tank 3 is controlled to rise and fall by the control machine 1. When the control machine 1 rises and falls, its top can be sealed by the sealing tank 2. The two sets of hoppers 16 are respectively connected to the two sets of conveying cylinders 13, and the two sets of hoppers 16 are respectively filled with silicon or graphite. When the sealing cover 4 is opened, the hoppers 16 can be filled with raw materials.

[0051] The design of the hopper 16 allows for the opening of the sealing cover 4 to add silicon and graphite to the interior of the two hoppers 16 respectively, without the need to measure the mass of silicon and graphite in advance. The material inside the hopper 16 is discharged from the bottom of the fixed pipe 5 by controlling the conveying cylinder 13, and the discharge amount of the material is automatically controlled. At the same time, there is no need to add external pipes. By controlling the position of the material to be discharged from the bottom of the fixed pipe 5, the space occupied by the feeding structure can be reduced.

[0052] Working principle:

[0053] First, silicon and graphite are added to the interiors of the two sets of hoppers 16 respectively. Simultaneously, the operation of the pneumatic cylinder 29 controls the support frame 30 to raise the movable plate 27. This, in turn, causes the limiting member 28 and the second movable member 24 to move upwards via the movable plate 27. The connecting shaft 33 then drives the sealing member 34 and the conveying cylinder 13 to move upwards. During the upward movement of the conveying cylinder 13, the baffle 14 pushes the first spring 20, causing the limiting circular plate 18 to move the first movable member 19 upwards until the first movable member 19 is pressed against the long rod 17. At this point, the baffle 14 slides upwards along the outer surface of the first movable member 19, causing the pressing member 21 to press against the connecting frame 35. This also causes the arc-shaped plate 23 to rotate along the inner side of the first slot 22, causing several sets of arc-shaped plates 23 to unfold simultaneously. Simultaneously, by controlling the rotation of the transmission shaft 11, the belt 12 and the rotating wheel 9 are connected... When the fixed tube 5 and the rotating part 7 rotate, the conveying cylinder 13 will rotate synchronously. When the conveying cylinder 13 rotates, it will drive the arc plate 23 to dig the raw material inside the hopper 16, so that the raw material can quickly enter the conveying cylinder 13 through the first slot 22. The raw material inside the conveying cylinder 13 will be weighed by the pressure sensor 10, and the feed amount of the two sets of conveying cylinders 13 will be controlled according to the set specific gravity. Through the operation of the threaded rod 32, the two sets of long rods 17 can be driven to move in opposite directions, thus changing the position of the limit member 28 pressing the second movable member 24. Under the elastic force of the second spring 25, the second movable member 24 will be driven to move downward, thereby driving the sealing member 34 and the pressure sensor 10 to separate from the conveying cylinder 13 through the connecting shaft 33. At this time, the raw material inside the conveying cylinder 13 can be discharged into the mixing tank 3, which is convenient for automatic control of the ratio of silicon to graphite.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
