Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery manufacturing, and more specifically, to a graphitized crucible grabbing device. Background Art

[0002] With the rapid development of the lithium battery industry, the production scale of lithium battery materials has been continuously expanded, and the requirements for production efficiency and working environment have become higher and higher. Graphitized crucible is a key equipment for the production of negative electrode materials in the manufacturing process of lithium batteries. It is mainly used to react lithium ions in the mixture with graphite compounds to prepare negative electrode materials. Graphitized crucibles are usually made of graphite materials, which have the characteristics of high temperature resistance, corrosion resistance and good conductivity. In the manufacturing process of lithium batteries, graphitized crucibles play an important role. As a reaction vessel, graphitized crucibles can withstand chemical reactions in high temperature environments. Graphitized crucibles have good electrical conductivity, which can promote charge transfer and ion diffusion, and improve the electrochemical properties of negative electrode materials. Graphitized crucibles can also resist corrosion and protect materials and equipment in the preparation process. When using graphitized crucibles to prepare negative electrode materials for lithium batteries, the graphitized crucibles need to be placed in a high-temperature furnace and graphitized under certain temperature and atmosphere conditions.

[0003] The production process of negative electrode materials for lithium battery materials is a very critical step, and the traditional method of grabbing graphitized crucibles can no longer meet the actual needs. In the traditional production process, the grabbing of graphitized crucibles has always been done manually. Specifically, personnel first use a crane and a wire rope to lift it, and then a special person needs to stand in the high-temperature furnace and manually put the wire rope on the crucible, and finally lift the crucible by the crane and carry it. There are many problems with this method. First, the operation in the furnace needs to be very cautious to prevent safety accidents, so the operation process is relatively slow and time-consuming. In addition, the accuracy of manual operation is not as good as that of mechanical equipment, and it may take multiple trial and error to complete, which undoubtedly increases the grabbing time and affects the overall production efficiency. Secondly, because of the need for manual grabbing, workers need to move crucibles weighing dozens of kilograms, which is easy to cause physical fatigue and work-related injuries. In addition, the temperature in the furnace is often very high and the working environment is very harsh, which undoubtedly increases the labor intensity of workers. Finally, the temperature inside the furnace is extremely high, and workers need to wear heat-insulating clothing to operate. In addition, the space inside the furnace is often small, which is a great challenge to the workers' physical fitness and psychological endurance. In addition, the space between the crucibles in the furnace is full of fillers, which makes cleaning difficult, and the high dust concentration will also damage the workers' respiratory system and is not good for their health.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0024] Reference Figures 1 to 4 As shown, the utility model discloses a device for grabbing a graphitized crucible. Specifically, the device comprises a lifting assembly, a first lifting plate 20, a guide rod, a graphitized crucible 60 and a rotary drive assembly 50; the lifting assembly is arranged above the first lifting plate 20, and the lifting assembly controls the first lifting plate 20 to perform lifting and lowering movements; a plurality of vertical guide rods are arranged below the first lifting plate 20, and the plurality of guide rods enclose a space for accommodating the crucible 60, wherein at least one of the guide rods is provided with a claw 301 at the bottom; the rotary drive assembly 50 is arranged on the first lifting plate 20, and a guide rod with a claw 301 is provided at the bottom, and the top of the guide rod is connected to the rotary drive assembly 50, and the guide rod is driven to rotate by the rotary drive assembly 50, so as to drive the claw 301 to rotate to the bottom of the graphitized crucible 60. A tooth structure is provided on the side of the claw 301 in contact with the graphitized crucible 60. The setting of the toothed structure can increase the friction between the claw 301 and the crucible 60, and for a smoother surface, the stability and firmness of the claw 301 can be improved. The first guide rod 30 and the second guide rod 40 are both made of 316L stainless steel, which can work continuously at high temperature without deformation, and the length of the second guide rod 40 is shorter than the first guide rod 30, so that the material cost can be saved. The bottom of the claw 301 is triangularly raised, which is convenient for inserting into the auxiliary material, and the length of the claw 301 is 50mm-200mm. The length of the claw 301 is designed to be 50mm-200mm, which can ensure that it can enter the auxiliary material smoothly and facilitate the rotation and operation of the claw 301. If the claw 301 is too long, it may not be easy to enter the auxiliary material, and it is inconvenient to operate, affecting the rotation. However, if the claw 301 is too short, it may affect the stability of the graphitized crucible.

[0025] Furthermore, the rotation drive assembly 50 includes a cylinder 501, a slider 502 and a first gear 503; the first gear 503 is sleeved on the first guide rod 30, the output end of the cylinder 501 is fixedly connected to the slider 502, and a first rack 504 meshing with the first gear 503 is provided on the side of the slider 502. The first gear 503 can be driven to rotate by the push of the cylinder 501, and the entire first guide rod 30 can be driven to rotate. When taking materials, the lifting device moves the first lifting plate 20 to the top of the graphitizing crucible 60, and then makes the first lifting plate 20 descend, and the first guide rod 30 drives the claw 301 to be inserted into the auxiliary material under the action of the sharp corner. When the bottom claw 301 exceeds the bottom surface of the graphitizing crucible 60, the second guide rod 40 is also inserted into the auxiliary material. At this time, the cylinder 501 pushes the first rack 504 on the slider 502 to move, and the first rack 504 drives the first gear 503 to rotate, and the first gear 503 drives the first guide rod 30 to rotate, and the claw 301 installed at the bottom of the first guide rod 30 can rotate to the bottom surface of the graphitizing crucible 60, and the lifting assembly raises the first lifting plate 20 as a whole, and the claw 301 can support the bottom surface of the graphitizing crucible 60 to bring the graphitizing crucible 60 out of the heating furnace, while the second guide rod 40 on the other side can prevent the graphitizing crucible 60 from tipping over, thereby ensuring that the graphitizing crucible 60 is taken out smoothly.

[0026] Furthermore, the lifting assembly includes a fixed frame 101, a movable frame 102, a reduction motor 103 and a second gear 104; the movable frame 102 is arranged inside the fixed frame 101, the movable frame 102 is slidably connected to the fixed frame 101, the bottom of the movable frame 102 is fixedly connected to the second lifting plate 20, the reduction motor 103 is installed on the top of the fixed frame 101, the output shaft 1031 of the reduction motor 103 is parallel to one side of the fixed frame 101, and the second gear 104 is fixedly installed on the output shaft 1031. The movable frame 102 is provided with a second rack 105 meshing with the second gear 104 on one side where the reduction motor 103 is installed. A rolling wheel 106 is arranged inside the fixed frame 101, the fixed end of the rolling wheel 106 is fixedly connected to the inside of the fixed frame 101, and the rolling end is slidably connected to the movable frame 102. This arrangement can provide a stable support point, so that the movable frame 102 can maintain balance and stability, and ensure that the movable frame 102 will not tilt or shake during movement. A limit plate 107 is also provided on the movable frame 102, and the length of the limit plate 107 is slightly greater than the distance from the outer side of the movable frame 102 to the inner side of the fixed frame 101, so that the moving range of the movable frame 102 can be limited, thereby ensuring that the mechanical parts will not exceed the predetermined range during movement, avoiding damage to the equipment or causing safety hazards.

[0027] The graphitization crucible grabbing device also includes a second lifting plate 70 and a connecting column 208, wherein the second lifting plate 70 and the first lifting plate 20 are fixedly connected via the connecting column 208, and the rotary drive assembly 50 is disposed between the second lifting plate 70 and the first lifting plate 20. When the lifting assembly is in operation, the reduction motor 103 rotates in the opposite direction, and the lifting assembly performs a lifting movement. The reduction motor 103 drives the shaft to rotate to rotate the second gear 104, and the second rack 105 meshing with the second gear 104 drives the movable frame 102, the second lifting plate 70 and the first lifting plate 20 to lift as a whole. At this time, the claw 301 supports the bottom of the graphitization crucible 60, and the first guide rod 30 and the second guide rod 40 limit the movement of the graphitization crucible 60 in all directions, effectively preventing the graphitization crucible 60 from tipping over, so that it can be smoothly removed from the furnace.

The dust cover 201 is provided with an air inlet pipe 202 and an air outlet pipe 203. Cooling gas is introduced from the air inlet pipe 202 and discharged from the air outlet pipe 203, so that the internal temperature is constant and high temperature will not occur. It can also form a positive pressure state inside to prevent dust from entering again.

[0029] The beneficial effects of the utility model are as follows: the device can replace manual labor to complete the grasping of the crucible and send it to a designated position, thereby improving work efficiency, reducing labor intensity, and preventing personnel from being in a high-temperature environment.
