Description

Technical Field

[0001] This invention relates to equipment for battery manufacturing, and more particularly to equipment and manufacturing method for new energy batteries, belonging to the field of new energy battery manufacturing technology. Background Technology

[0002] In the field of new energy battery manufacturing, high-temperature sintering of electrode materials, solid electrolytes and positive and negative electrode precursor powders is one of the core processes that determines battery performance. The compositional uniformity, crystal phase consistency and particle morphology of the sintered products directly affect the battery's capacity, cycle life and safety.

[0003] Currently, static sagger furnaces or rotary kilns are widely used for sintering new energy battery materials. In static sagger furnaces, powder is loaded into saggers and pushed into the kiln for heating. The material is stationary during sintering, and heat is conducted from the outside to the inside, which easily creates a temperature gradient. This leads to inconsistent sintering degrees between the surface and core materials. At the same time, the powder itself does not undergo relative movement, making it prone to component segregation due to gravity settling, which seriously affects batch consistency and product yield. Although rotary kilns can tumble the material by rotating the cylinder, they can only rotate around a single horizontal axis. The material passively falls within the cross-section of the cylinder, resulting in a single tumbling mode and obvious "dead zones" and "centrifugal stratification" phenomena, making it difficult to achieve sufficient mixing of powder in three-dimensional space. In addition, rotary kilns rely on rollers and support rollers at both ends of the cylinder for support, resulting in high rotational resistance and energy consumption. Moreover, the rollers and support rollers wear out severely after long-term operation, leading to high maintenance costs.

[0004] In terms of transmission control, the drive mechanism of existing equipment is mostly rigidly connected, which places extremely stringent requirements on the processing and assembly precision of parts. During operation, when the furnace body undergoes slight displacement due to thermal expansion or material eccentricity, the drive components are difficult to adaptively adjust, and are prone to failures such as contact force fluctuation, slippage, or even jamming.

[0005] Therefore, it is urgent to improve the equipment used in the manufacturing of new energy batteries in order to solve the above-mentioned problems. Summary of the Invention

[0006] The purpose of this invention is to provide a device and method for manufacturing new energy batteries. Through two orthogonally distributed drive mechanisms, it can flexibly realize various motion modes such as pure horizontal rotation, pure vertical flipping, and compound nutation tumbling, so that the materials in the spherical sintering furnace can be uniformly mixed and heated in three-dimensional space without dead angles, effectively avoiding component segregation and local overburning.

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include: A new energy battery manufacturing equipment includes symmetrically distributed support plates and a spherical sintering furnace that is rolled between the support plates. The support plates are provided with driving mechanisms, and two driving mechanisms are vertically distributed. One driving mechanism is used to rotate the spherical sintering furnace horizontally, and the other driving mechanism is used to rotate the spherical sintering furnace vertically. The driving mechanism includes a drive motor and a drive shaft disposed at the output end of the drive motor. A drive ball is fixedly disposed on the drive shaft. A drive groove is provided on the outer side of the support plate. A drive hole is provided in the middle of the drive groove. The drive ball passes through the drive hole and abuts against the outer side of the spherical sintering furnace. The end of the drive motor away from the drive shaft is rotatably connected to a connecting rod support block via a motor connecting rod. The end of the drive shaft away from the drive motor is fitted with a support ring, and a miniature electric telescopic rod is connected to the support ring. When the miniature electric telescopic rod retracts, the drive ball abuts against the outer surface of the spherical sintering furnace and drives the spherical sintering furnace to rotate. When the miniature electric telescopic rod extends, the drive ball retracts from the outer surface of the spherical sintering furnace. Both the miniature electric telescopic rod and the connecting rod support block are fixedly mounted on the support plate.

[0008] Preferably, the spherical sintering furnace has an eccentric counterweight structure, the center of mass of which has a predetermined eccentric distance from the center of the sphere in the vertical direction, and the center of mass is closer to the bottom of the spherical sintering furnace relative to the center of the sphere. Based on this eccentric counterweight structure, the spherical sintering furnace has a self-resetting characteristic in a static state. When the center of mass of the spherical sintering furnace is higher than its center of mass, the spherical sintering furnace rolls under the action of gravity until its center of mass is lowered to the lowest potential energy point, so as to realize the automatic positioning of the bottom of the spherical sintering furnace to the support surface.

[0009] Preferably, the upper end of the spherical sintering furnace is provided with a feed port and connected to an upper sealing cover by threads, the bottom of the spherical sintering furnace is provided with a discharge port and connected to a lower sealing cover by threads, the outer side of the upper sealing cover is provided with an upper cross brake groove, and the outer side of the lower sealing cover is provided with a lower cross brake groove.

[0010] Preferably, the upper sealing cover has an exhaust chamber inside, and the lower side of the upper sealing cover has a plurality of lower exhaust holes that communicate with the interior of the exhaust chamber. The upper sealing cover has a purification chamber inside, one end of which communicates with the bottom surface of the upper cross brake groove, and the purification chamber has a plurality of upper exhaust holes that communicate with the exhaust chamber. An exhaust ball is rolled inside the exhaust chamber. When the upper sealing cover is above the spherical sintering furnace, the exhaust ball abuts against the lower exhaust hole. When the upper sealing cover is below the spherical sintering furnace, the exhaust ball abuts against the upper exhaust hole.

[0011] Preferably, the purification chamber is connected to a breathable grille cover at its port, and the interior of the purification chamber is filled with activated carbon.

[0012] Preferably, a neodymium magnet is fixedly provided on the inner side of the lower sealing cover, and a stirring ball that works in conjunction with the neodymium magnet is provided inside the spherical sintering furnace.

[0013] Preferably, the two support plates are fixedly connected by symmetrically distributed support arms, and each support arm is provided with a heating mechanism. The heating mechanism includes a heating cover provided on the output shaft of the heating cover telescopic rod, a heating plate fixedly provided on the heating cover, the heating plate being used to heat the spherical sintering furnace, and the heating cover telescopic rod being fixedly provided on the support arm, the heating cover telescopic rod being used to horizontally push the heating cover.

[0014] Preferably, the support plate has a rotating groove on one side near the spherical sintering furnace, and the drive groove has multiple ventilation holes inside. The drive groove is connected to the rotating groove through the ventilation holes, and a cooling fan is installed inside the ventilation holes. A support rod for supporting the support plate is fixedly installed inside the drive groove.

[0015] Preferably, the rotating groove corresponds to the outer surface of the spherical sintering furnace, and a plurality of supporting ball grooves are provided on the rotating groove. A limiting supporting ball is rotatably arranged inside the supporting ball groove, and the limiting supporting ball abuts against the outer surface of the spherical sintering furnace.

[0016] A method for manufacturing a new energy battery includes the following steps: Step 1: Load the new energy battery material to be sintered into the spherical sintering furnace through the feed port and tighten the top sealing cover; Step 2: Start the heating mechanism, push the heating cover close to the spherical sintering furnace through the extension rod of the heating cover, and use the heating plate to heat the spherical sintering furnace; Step 3: Activate two vertically distributed drive mechanisms. The drive motor drives the drive ball and the micro electric telescopic rod to alternately contact the outer surface of the spherical sintering furnace, thereby realizing the horizontal and vertical rotation of the spherical sintering furnace and ensuring that the internal material is heated evenly. Step 4: During the sintering process, the internal gas pressure is automatically regulated by the cooperation of the exhaust chamber and the exhaust ball, and the exhaust gas is purified by the activated carbon in the purification chamber. Step 5: After sintering is completed, first turn off the heating mechanism, then move the heating cover away from the spherical sintering furnace using the heating cover telescopic rod, and then start the cooling fan to gradually cool the spherical sintering furnace. After the spherical sintering furnace has cooled down, unscrew the lower sealing cover and discharge the sintered material from the discharge port.

[0017] The present invention has at least the following beneficial effects: 1. Through two orthogonally distributed drive mechanisms, various motion modes such as pure horizontal rotation, pure vertical flipping, and compound nutation tumbling can be flexibly realized, so that the materials in the spherical sintering furnace can be uniformly mixed and heated in three-dimensional space without dead angles, effectively avoiding component segregation and local overburning.

[0018] 2. The hinged floating installation at the tail of the drive motor enables adaptive centering, reducing the requirements for machining accuracy. The drive balls adopt point contact transmission to reduce wear. When the machine stops, all drive balls retract, and the spherical sintering furnace automatically resets to a safe posture with the feed port facing upwards thanks to the eccentric counterweight. In addition, it also has controllable damping braking to achieve precise positioning. Overall, it has excellent sintering homogeneity, transmission reliability and operational safety.

[0019] 3. The entire switching process requires no solenoid valves, sensors, or program control. It relies on the principle of pure mechanical gravity to achieve automatic switching with zero power consumption and zero delay, which greatly improves the reliability and maintenance-free nature of the system in high-temperature and harsh environments.

[0020] 4. By shutting off the heating mechanism and moving the heating hood away from the spherical sintering furnace, and with the help of a cooling fan, the cooling waiting time can be significantly shortened, achieving multi-stage cooling of the spherical sintering furnace and effectively preventing thermal stress cracking of the furnace body and abrupt changes in the crystal phase of the sintered products caused by rapid cooling.

[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] like Figures 1-11 As shown, the new energy battery manufacturing equipment provided in this embodiment includes symmetrically distributed support plates 2 and a spherical sintering furnace 1 that is rolled between the support plates 2. The support plates 2 are provided with drive mechanisms 3. The two drive mechanisms 3 are vertically distributed, so that the spherical sintering furnace 1 can be controlled to rotate in two independent degrees of freedom, horizontal rotation and vertical flipping, thereby realizing multi-dimensional, dead-angle-free uniform tumbling motion. It is particularly suitable for mixing and sintering powder or granular materials, effectively avoiding component segregation or local overburning caused by material settling due to gravity. One drive mechanism 3 is used to rotate the spherical sintering furnace 1 horizontally, and the other drive mechanism 3 is used to rotate the spherical sintering furnace 1 vertically. The spherical sintering furnace 1 adopts a rolling support method. Compared with traditional fixed kilns, the rotation resistance is extremely small and the energy consumption is lower. Moreover, the furnace body itself can use gravity to continuously tumble the material during rotation, improving heat transfer efficiency and material homogeneity. The drive mechanism 3 includes a drive motor 301 and a drive shaft 303 located at the output end of the drive motor 301. A drive ball 302 is fixedly mounted on the drive shaft 303. A drive groove 201 is opened on the outer side of the support plate 2. A drive hole 204 is opened in the middle of the drive groove 201. The drive ball 302 passes through the drive hole 204 and abuts against the outer side of the spherical sintering furnace 1. As the main friction transmission element, the drive ball 302 passes through the drive hole 204 and forms point contact or small area contact with the outer surface of the spherical sintering furnace 1. Under the premise of ensuring sufficient friction, the mechanical damage and wear on the outer wall of the furnace body are minimized, and the equipment life is extended. The end of the drive motor 301 furthest from the drive shaft 303 is rotatably connected to a connecting rod support block 305 via a motor connecting rod 304. A support ring 306 is fitted onto the end of the drive shaft 303 furthest from the drive motor 301. The tail of the drive motor 301 is not rigidly locked; the overall axis of the drive motor 301 can automatically adjust its angle according to the position change of the spherical sintering furnace 1. This prevents sudden changes in contact force or even loss of contact due to rigid alignment deviations. This flexible, adaptive installation method significantly reduces the equipment's reliance on machining and assembly precision. To meet stringent requirements, a miniature electric telescopic rod 307 is connected to the support ring 306. When the miniature electric telescopic rod 307 retracts, the driving ball 302 abuts against the outer surface of the spherical sintering furnace 1 and drives the spherical sintering furnace 1 to rotate. When the miniature electric telescopic rod 307 extends, the driving ball 302 retracts from the outer surface of the spherical sintering furnace 1. When the miniature electric telescopic rod 307 retracts, the driving ball 302 presses against the outer surface of the spherical sintering furnace 1 to form a friction driving point, thereby driving the spherical sintering furnace 1 to rotate or flip. In addition, in order to achieve the purposes of horizontal rotation, vertical flipping and compound motion respectively, one of the two drive mechanisms 3 is a horizontal drive mechanism and the other is a vertical drive mechanism; The miniature electric telescopic rod 307 in each drive mechanism is sleeved on the support ring 306 of the drive shaft 303. Its contraction or extension will change the radial position of the drive ball 302 relative to the outer surface of the spherical sintering furnace 1. When the miniature electric telescopic rod 307 retracts, it pushes the drive shaft 303 and the drive ball 302 close to the surface of the spherical sintering furnace 1, so that the drive ball 302 and the spherical sintering furnace 1 generate sufficient positive pressure and form effective frictional contact. At this time, the drive mechanism has driving force. When the miniature electric telescopic rod 307 extends: the drive shaft 303 and the drive ball 302 slightly retract from the surface of the spherical sintering furnace 1 under the action of the miniature electric telescopic rod 307, the positive pressure decreases or even becomes zero, and the drive ball 302 is in a state of separation or non-contact with the furnace body. At this time, the drive mechanism does not transmit driving force, and the spherical sintering furnace 1 can rotate freely in this direction. Therefore, the following state can be achieved: In a purely horizontal rotation state, the miniature electric telescopic rod 307 on the horizontal drive mechanism retracts, the drive ball 302 is in close contact with the spherical sintering furnace 1 and has driving force, the drive ball 302 of the vertical drive mechanism is separated from the spherical sintering furnace 1 and does not participate in the drive, the drive ball 302 applies tangential friction force on the horizontal equatorial plane of the spherical sintering furnace 1 and pushes the spherical sintering furnace 1 to rotate around its vertical central axis; In the pure vertical flipping state, the vertical drive mechanism: the miniature electric telescopic rod 307 retracts, the drive ball 302 is in close contact with the spherical sintering furnace 1 and has driving force, the drive ball 302 of the horizontal drive mechanism is separated from the spherical sintering furnace 1 and does not participate in the drive, only the vertical drive mechanism works, the drive ball 302 applies tangential friction force on the vertical meridian surface of the spherical sintering furnace 1, and pushes the spherical sintering furnace 1 to flip around its horizontal central axis; In the composite motion state, the miniature electric telescopic rods 307 of both the horizontal and vertical drive mechanisms retract, the drive ball 302 is in close contact with the spherical sintering furnace 1, and both have driving force. The two drive motors 301 operate simultaneously according to the set speed ratio and phase difference. The spherical sintering furnace 1 is simultaneously subjected to tangential frictional forces in two orthogonal directions. Its composite motion is a rotation around a spatial oblique axis, i.e., nutation tumbling, which allows the material in the spherical sintering furnace 1 to achieve the most thorough mixing and tumbling in three-dimensional space, avoiding the "dead zone" or "centrifugal stratification" phenomenon that may occur when rotating in a single direction. In the unloaded free reset state, the miniature electric telescopic rods 307 of both the horizontal and vertical drive mechanisms extend, the drive ball 302 retracts from the spherical sintering furnace 1, and both drive motors 301 stop working. Under the gravity of the eccentric counterweight of the spherical sintering furnace 1, the furnace body automatically rolls to the lowest potential energy balance position, realizing mechanical self-reset, which facilitates loading and unloading and ensures safety. In the semi-constrained damping state, one of the miniature electric telescopic rods 307 partially retracts, causing the drive ball 302 to make slight contact with the spherical sintering furnace 1, generating controllable damping friction force, but not completely locking up. The drive ball 302 on the other drive mechanism is completely separated from the spherical sintering furnace 1, and the spherical sintering furnace 1 is slowly braked by friction damping, so as to avoid material impact or overshoot of the spherical sintering furnace 1 due to inertia during emergency stop, which helps to accurately stop the spherical sintering furnace 1 at the preset position. The miniature electric telescopic rod 307 and the connecting rod support block 305 are both fixedly mounted on the support plate 2. The positioning and installation layout ensures that the entire drive mechanism 3 will not drift due to vibration or gravity during long-term operation, maintaining the precise relative position between the drive ball 302 and the spherical sintering furnace 1, and ensuring the repeatability and reliability of the transmission. Through two orthogonally distributed drive mechanisms 3, various motion modes such as pure horizontal rotation, pure vertical flipping, and compound nutation tumbling can be flexibly realized, so that the material in the spherical sintering furnace 1 can be uniformly mixed and heated in three-dimensional space without dead angles, effectively avoiding component segregation and local overburning. Meanwhile, the hinged floating installation at the tail of the drive motor 301 enables adaptive centering, reducing the requirements for machining accuracy. The drive ball 302 adopts point contact transmission to reduce wear. When the machine stops, all drive balls 302 retract, and the spherical sintering furnace 1 automatically resets to a safe posture with the feed port 101 facing upwards thanks to the eccentric counterweight. In addition, it also has controllable damping braking to achieve precise positioning. Overall, it has excellent sintering homogeneity, transmission reliability and operational safety.

[0025] Furthermore, such as Figure 1 As shown, the spherical sintering furnace 1 has an eccentric counterweight structure, with its center of mass and the center of the sphere having a preset eccentric distance in the vertical direction, and the center of mass is closer to the bottom of the spherical sintering furnace 1 relative to the center of the sphere. After the equipment stops, the power is cut off, or an emergency brake is applied, the spherical sintering furnace 1 will automatically roll to a stable equilibrium position. Based on this eccentric counterweight structure, the spherical sintering furnace 1 has a self-resetting characteristic in a static state. When the center of mass of the spherical sintering furnace 1 is higher than its sphere center, the spherical sintering furnace 1 rolls under the action of gravity until its center of mass is lowered to the lowest potential energy point, so that the bottom of the spherical sintering furnace 1 is automatically positioned to the support surface. After the machine stops, the feed port 101 automatically faces upward, and the next batch of material can be directly loaded without manual alignment. There is no need to configure additional locking or reset mechanisms. The passive reset is achieved entirely by gravity, which reduces manufacturing costs and control complexity. At the same time, the eccentric counterweight structure also means that during the rotation, the gravitational torque will continuously participate in the dynamic behavior of the furnace body, so that the load of the drive mechanism 3 in the vertical rotation direction presents a periodic change. This helps to use gravity to assist the rolling and peeling of materials in the furnace, reduce the phenomenon of sticking to the wall, and also helps to achieve the above-mentioned no-load free reset state.

[0026] Furthermore, such as Figure 1 As shown, the upper end of the spherical sintering furnace 1 is provided with a feed port 101 and is connected to an upper sealing cover 4 by threads. The bottom of the spherical sintering furnace 1 is provided with a discharge port 102 and is connected to a lower sealing cover 5 by threads. The sealing cover with threaded connection can withstand a certain positive or negative pressure that may be generated inside during the sintering process, with high sealing reliability and convenient disassembly and assembly without special tools. The outer side of the upper sealing cover 4 is provided with an upper cross brake groove 401, and the outer side of the lower sealing cover 5 is provided with a lower cross brake groove 501, so that torque can be applied by a special wrench when tightening the sealing cover, which is convenient to operate. At the same time, during the rotation of the spherical sintering furnace 1, the cross groove can also be used as a positioning mark. Meanwhile, the upper sealing cover 4 also features a passive intelligent reversing exhaust system, such as... Figure 1 and Figure 7 As shown, an exhaust chamber 402 is provided inside the upper sealing cover 4. Multiple lower exhaust holes 4022 connected to the interior of the exhaust chamber 402 are provided on the lower side of the upper sealing cover 4. A purification chamber 403 is provided inside the upper sealing cover 4. One end of the purification chamber 403 is connected to the bottom surface of the upper cross brake groove 401. Multiple upper exhaust holes 4021 connected to the exhaust chamber 402 are provided on the purification chamber 403. An exhaust ball 11 is rolled inside the exhaust chamber 402. The exhaust ball 11 is a freely rolling spherical valve core. Its position is determined entirely by gravity. Therefore, it can automatically switch the exhaust path according to the real-time attitude of the spherical sintering furnace 1. When the upper sealing cover 4 is located above the spherical sintering furnace 1, the exhaust ball 11 abuts against the lower exhaust hole 4022. When the furnace body is in working position and the feed port 101 is facing upward, the exhaust ball 11 rolls down and blocks the lower exhaust hole 4022. At this time, the gas in the spherical sintering furnace 1 can only be discharged through the upper exhaust hole 4021, the purification chamber 403, and the outside, thus achieving forced purification and discharge. When the upper sealing cover 4 is located below the spherical sintering furnace 1, the exhaust ball 11 abuts against the upper exhaust hole 4021. When the spherical sintering furnace 1 is inverted and the feed port 101 faces downward, the exhaust ball 11 blocks the upper exhaust hole 4021. At this time, the lower exhaust hole 4022 is connected to the exhaust chamber 402, but the bottom opening has been sealed by the sealing cover. Therefore, it actually plays a dual safety role of sealing the internal space and preventing material leakage. The entire switching process requires no solenoid valves, sensors, or program control. It relies on the principle of pure mechanical gravity to achieve automatic switching with zero power consumption and zero delay, which greatly improves the reliability and maintenance-free nature of the system in high-temperature and harsh environments. In addition, a breathable grille cover 4031 is connected to the port of the purification chamber 403. The interior of the purification chamber 403 is filled with activated carbon, and an activated carbon adsorption layer is integrated in the exhaust path. It can effectively adsorb volatile organic compounds, acidic gases or odor components generated during sintering, and achieve clean emissions. The breathable grille cover 4031 not only ensures the smooth flow of gas, but also prevents activated carbon particles from being carried out by the airflow or falling into the spherical sintering furnace 1. The structure is simple and easy to replace. Moreover, such as Figure 8 As shown, a neodymium magnet 502 is fixedly installed on the inner side of the lower sealing cover 5. The spherical sintering furnace 1 is equipped with a stirring ball 8 that works in conjunction with the neodymium magnet 502. The neodymium magnet 502 is fixed on the lower sealing cover 5 and rotates or flips with the furnace body to actively impact and stir the powder material, effectively breaking up agglomerates, promoting uniform mixing and heat exchange between particles, and significantly improving the compositional uniformity and crystal phase consistency of the sintered product.

[0027] Furthermore, such as Figure 6 and Figure 9As shown, the two support plates 2 are fixedly connected by symmetrically distributed support arms 12. Each support arm 12 is equipped with a heating mechanism 6. The heating mechanism 6 includes a heating cover 601 set on the output shaft of the heating cover telescopic rod 602. A heating plate 603 is fixedly set on the heating cover 601. The heating plate 603 is used to heat the spherical sintering furnace 1. The heating cover telescopic rod 602 is fixedly set on the support arm 12. The heating cover telescopic rod 602 is used to horizontally push the heating cover 601. The two heating mechanisms 6 are symmetrically distributed on the support arm 12, which can radiate heat from both sides of the spherical sintering furnace 1 at the same time, so that the spherical sintering furnace 1 is heated more evenly, avoiding the temperature gradient caused by unilateral heating, which is beneficial to improving the sintering quality. In order to achieve multi-stage cooling of the spherical sintering furnace 1 after sintering; First, the heating plate 603 is turned off to stop heating the spherical sintering furnace 1, which is in a preliminary cooling state; Then, the heating hood 601 retracts, exposing the spherical sintering furnace 1 to ambient air, further accelerating the cooling of the spherical sintering furnace 1; Furthermore, a rotating groove 205 is provided on one side of the support plate 2 near the spherical sintering furnace 1, and multiple ventilation holes 203 are provided inside the drive groove 201. The drive groove 201 is connected to the rotating groove 205 through the ventilation holes 203. A cooling fan 10 is provided inside the ventilation holes 203. With the help of the cooling fan 10, the cooling waiting time can be greatly shortened and the production efficiency can be improved. Therefore, the purpose of multi-stage cooling of the spherical sintering furnace 1 can be achieved. The drive slot 201 is fixedly equipped with a support rod 9 for supporting the support plate 2, which ensures that the relative positional accuracy between the drive ball 302 and the spherical sintering furnace 1 remains stable over a long period of time.

[0028] Finally, as Figure 1 and Figure 5 As shown, the rotating groove 205 corresponds to the outer side of the spherical sintering furnace 1. Multiple support ball grooves 2051 are provided on the rotating groove 205. Limiting support balls 7 are rotatably arranged inside the support ball grooves 2051. The multiple limiting support balls 7 form multi-point rolling support in the rotating groove 205, which transforms the sliding friction between the spherical sintering furnace 1 and the support plate 2 into rolling friction, greatly reducing the rotational resistance and reducing the energy consumption of the drive motor 301. At the same time, it avoids scratching the outer wall of the spherical sintering furnace 1. The limiting support balls 7 abut against the outer side of the spherical sintering furnace 1. The limiting support balls 7 also play a limiting and guiding role, ensuring that the spherical sintering furnace 1 will not deviate from the preset rolling trajectory during rotation, maintaining the centered position of the spherical sintering furnace 1 between the two support plates 2, and preventing the drive ball 302 from disengaging or the sealing cover from colliding due to axial movement.

[0029] like Figures 1-11As shown, the manufacturing method of the new energy battery provided in this embodiment includes the following steps: Step 1: Load the new energy battery material to be sintered into the spherical sintering furnace 1 through the feed port 101, and tighten the upper sealing cover 4. Step 2: Start the heating mechanism 6, push the heating cover 601 close to the spherical sintering furnace 1 through the heating cover telescopic rod 602, and use the heating plate 603 to heat the spherical sintering furnace 1; Step 3: Start the two vertically distributed drive mechanisms 3. Drive the drive ball 302 and the micro electric telescopic rod 307 to alternately contact the outer surface of the spherical sintering furnace 1 through the drive motor 301, so as to realize the horizontal and vertical rotation of the spherical sintering furnace 1 respectively, so that the internal material is heated evenly. Step 4: During the sintering process, the internal gas pressure is automatically adjusted by the cooperation of the exhaust chamber 402 and the exhaust ball 11, and the exhaust gas is purified by the activated carbon in the purification chamber 403. Step 5: After sintering is completed, first turn off the heating mechanism 6, then move the heating cover 601 away from the spherical sintering furnace 1 using the heating cover telescopic rod 602, and then start the cooling fan 10 to gradually cool the spherical sintering furnace 1. After the spherical sintering furnace 1 has cooled down, unscrew the lower sealing cover 5 and discharge the sintered material from the discharge port 102. This effectively prevents thermal stress cracking of the furnace body caused by rapid cooling and abrupt changes in the crystal phase of the sintered product. The whole method makes full use of the structural characteristics of the equipment, such as eccentric reset, automatic exhaust reversal, and magnetic stirring, to achieve a highly automated sintering process with minimal human intervention, which is beneficial to process consistency and quality control in mass production.
