Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a separation device for a sintering crucible for lithium battery cathode materials. Background Technology

[0002] Battery cathode materials are a key component for providing lithium ions in batteries. Sintering of cathode materials is a crucial step in battery manufacturing. High-temperature sintering can make the crystal structure of the cathode material more regular, increasing its crystallinity and thus enhancing its stability. This allows it to better withstand volume changes and structural stresses during charging and discharging. Through sintering, the specific capacity, operating voltage, and other electrochemical properties of the cathode material can be significantly improved, thereby increasing the battery's energy density and charge / discharge efficiency. During sintering, various elements can fully diffuse and react, forming a uniform compound, reducing impurities and defects, and improving the purity and uniformity of the material. In sintering, the cathode material is contained in a sintering crucible. After sintering, the cathode material is placed inside the crucible. However, after sintering, the cathode material tends to agglomerate within the crucible, requiring a separation device to reduce agglomeration. However, this method still has the following drawbacks in practical use:

[0003] When separating the sagger from the sintered positive electrode material, the positive electrode material inside the sagger is directly cut with a cutter. As the positive electrode material inside the sagger is sintered, it is easy for caking to occur. The separation effect between the positive electrode material in the sagger and the sagger is not good enough, which affects the subsequent sagger turning operation.

[0004] Secondly, in order to cut, the sagger needs to be moved to the separation position on the separation device. However, during operation, the separation position of the sagger can only be roughly determined, and it is not convenient to move the sagger to the position where it is aligned with the separation device. Utility Model Content

[0005] The purpose of this utility model is to provide a separation device for sintering crucibles of lithium battery cathode materials. By setting a fixed outer shell, a fixed plate and a limiting platform, it solves the problems that the separation effect of the crucible separation device on the cathode material after sintering is not good enough and that it is not convenient to align the crucible with the separation position.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a separation device for sintering saggers of lithium battery cathode materials, comprising a fixed outer shell, a fixed plate, and a limiting platform. A side plate is fixed to one side of the fixed outer shell. Driven wheels are rotatably connected at equal intervals along a center line parallel to the long side of the side plate near the center of the fixed outer shell. A sagger body is mounted on top of the driven wheels. A limiting platform is movably connected to the bottom of the fixed outer shell on one side of the sagger body. A connecting plate is mounted on the bottom of the limiting platform. An electric push rod II is fixed to the center of the bottom of the connecting plate. The telescopic end of the electric push rod II passes through the connecting plate and is fixed to the bottom of the limiting platform. A fixed plate is mounted above the sagger body. An electric push rod is fixed to the center of the bottom of the plate. A fixed plate is fixed to the telescopic end of the electric push rod. A compression spring is fixed to the bottom of the fixed plate. A lifting plate is fixed to the bottom of the compression spring. Three cutters are fixed at equal intervals along the center line parallel to the short side at the bottom of the lifting plate. During operation, the driving wheel and the driven wheel are connected to the fixed housing, which provides the transport space for the sagger body. The electric push rod is connected to the top of the fixed plate, which drives the fixed plate to descend. The compression spring drives the lifting plate and the cutters to move down synchronously into the sagger body to cut the positive electrode material of the battery in the sagger body. The limiting platform restricts the position of the sagger body in the fixed housing by lifting.

[0008] Furthermore, a connecting shaft is movably connected at equal intervals to the lower part of the fixed housing on the side away from the side plate. A drive wheel is fixed to one end of the connecting shaft near the inside of the fixed housing. The height of the drive wheel is the same as that of the driven wheel. The connecting shaft on the fixed housing is connected to the structure that drives the rotation. Under the drive of the structure, the drive wheel is driven to rotate, causing the sagger to move inside the fixed housing.

[0009] Furthermore, an opening is provided on one side of the fixed housing, and a movable opening is provided at the bottom of the fixed housing corresponding to the position of the limiting platform. The limiting platform is movably connected in the movable opening. The opening of the fixed housing provides visual operation of the internal space of the fixed housing, and the fixed housing is movably connected to the limiting platform through the movable opening.

[0010] Furthermore, the fixing plate is fixed inside the fixing shell, and a flexible protective cover is fixed at the bottom center of the fixing plate. The bottom end of the flexible protective cover is fixed to the top of the lifting plate, and two vibration motors are fixed at the top of the lifting plate inside the flexible protective cover. The two vibration motors are placed on both sides of the compression spring. When the fixing plate is working, the flexible protective cover protects the vibration motors and the electric push rod.

[0011] Furthermore, the connecting plate is fixed to the bottom of the fixed housing, and mounting plates are fixed to the two short sides of the top of the limiting platform. The connecting plate supports the limiting platform by being fixed to the bottom of the housing, and the mounting plate is connected to the rotating rod.

[0012] Furthermore, two rotating rods are rotatably connected to the upper part of the two mounting plates on their adjacent sides. Support wheels are fixed at both ends of the rotating rods, and the support wheels cooperate to support the movement of the crucible after cutting the internal battery positive electrode material.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of insufficient separation effect of sintered positive electrode material by setting a fixed outer shell and a fixed plate. After the sagger body is transported into the fixed outer shell and supported by the driven wheel and the driving wheel, the sagger body moves to the appropriate position. The electric push rod is activated, which drives the fixed plate to descend, driving the compression spring and the lifting plate to descend until the cutter descends into the sagger body and inserts the sintered positive electrode material into the sagger body. At the same time, the vibration motor is activated, which drives the lifting plate to vibrate, driving the cutter to vibrate, and the positive electrode material in the sagger body is vibrated and dispersed, so that the sagger separation device can better separate the sintered positive electrode material.

[0015] This invention solves the problem of inconvenient positioning for sagger alignment and separation by setting a fixed outer shell and a limiting platform. When it is necessary to limit the position of the sagger body within the fixed outer shell, the electric push rod two is activated to drive the limiting platform upward. As the limiting platform rises, it drives the mounting plate upward. When the sagger body moves to contact the limiting platform and the mounting plate, the position of the sagger body is fixed. After the cutting and dispersing of the battery positive electrode material inside the sagger body is completed, the electric push rod two is restarted to drive the limiting platform downward. When the limiting platform descends and rests on the connecting plate, the rotation of the drive wheel drives the rotation of the support wheel until the sagger body moves into the sagger-turning device, making the positioning for sagger alignment and separation more convenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0027] Please see Figure 1-7This utility model relates to a separation device for sintering saggers of lithium battery cathode materials. It includes a fixed outer shell 1, a fixed plate 2, and a limiting platform 3. A side plate 101 is fixed to one side of the fixed outer shell 1, which serves to fix the plate 2 and the limiting platform 3. The inner side plate 101 supports the sagger body 4 via driven wheels 102. Driven wheels 102 are rotatably connected to the side of the side plate 101 near the center of the fixed outer shell 1, rotating at equal intervals along a centerline parallel to the long side. The driven wheels 102 support the lower part of the sagger body 4 on the side away from the driving wheel 104. The sagger body 4 is positioned on top of the driven wheels 102, containing the sintered cathode material. The limiting platform 3 is movably connected to the bottom of the fixed outer shell 1 on one side of the sagger body 4. The limiting platform 3 restricts the sagger body 4 within the fixed outer shell 1 and determines its position. A connecting plate 304 is provided at the bottom of the limiting platform 3, connecting an electric push rod to the bottom of the fixed outer shell 1. An electric push rod 305 is fixed to the center of the bottom of the connecting plate 304. The telescopic end of the electric push rod 305 passes through the fixed plate 2 and is fixed to the bottom of the limiting platform 3. The electric push rod 305 drives the limiting platform 3 to rise and fall within the fixed housing 1. A fixed plate 2 is provided above the main body 4 of the sagger. The fixed plate 2 is connected to an electric push rod 201. An electric push rod 201 is fixed to the center of the bottom of the fixed plate 2. A fixed plate 202 is fixed to the telescopic end of the electric push rod 201. A compression spring 203 is fixed to the bottom of 02, and a lifting plate 204 is fixed to the bottom of the compression spring 203. Three cutters 205 are fixed at equal intervals along the center line parallel to the short side at the bottom of the lifting plate 204. The electric push rod 201 drives the fixed plate 202 to descend, and as the fixed plate 202 descends, it drives the compression spring 203 and the lifting plate 204 to descend until the cutters 205 at the bottom of the lifting plate 204 enter the crucible body 4 to cut the positive electrode material in the crucible body 4 to a certain extent.

[0028] Specifically, a connecting shaft 103 is movably connected at equal intervals to the lower part of the fixed housing 1 on the side away from the side plate 101. A drive wheel 104 is fixed to one end of the connecting shaft 103 near the inside of the fixed housing 1. The height of the drive wheel 104 is the same as that of the driven wheel 102. The end of the connecting shaft 103 on the outside of the fixed housing 1 is connected to the device that drives the rotation. When the connecting shaft 103 rotates during operation, it drives the drive wheel 104 to rotate, thereby driving the sagger body 4 to move in the fixed housing 1.

[0029] Furthermore, an opening 105 is provided on one side of the fixed housing 1, and a movable opening 106 is provided at the bottom of the fixed housing 1 corresponding to the position of the limiting platform 3. The limiting platform 3 is movably connected inside the movable opening 106. The opening 105 on the fixed housing 1 provides access for the sagger body 4 to enter and exit, and the movable opening 106 is movably connected to the limiting platform 3.

[0030] Furthermore, the fixing plate 2 is fixed inside the fixing shell 1. A flexible protective cover 207 is fixed at the bottom center of the fixing plate 2. The bottom end of the flexible protective cover 207 is fixed to the top of the lifting plate 204. Two vibration motors 206 are fixed to the top of the lifting plate 204 inside the flexible protective cover 207. The two vibration motors 206 are placed on both sides of the compression spring 203. The flexible protective cover 207 on the fixing plate 2 protects the vibration motors 206 and electric push rods on the top of the lifting plate 204. The vibration motors 206 drive the lifting plate 204 to generate high-frequency vibration, which helps the cutter 205 to break up the clumps of material. The compression spring 203 buffers the fixing plate 202.

[0031] The operation process of this embodiment is as follows: During operation, the drive structure connected to the connecting shaft 103 on the fixed housing 1 is activated. After the sagger body 4 is transported into the fixed housing 1, it is supported by the driven wheel 102 and the driving wheel 104. The sagger body 4 moves to a suitable position, and the electric push rod 201 is activated. The electric push rod 201 drives the fixed plate 202 to descend, which in turn drives the compression spring 203 and the lifting plate 204 to descend until the cutter 205 descends into the sagger body 4 and inserts the battery positive electrode sintering material into the sagger body 4. At the same time, the vibration motor 206 is activated. The vibration motor 206 drives the lifting plate 204 to vibrate, which in turn drives the cutter 205 to vibrate, thus breaking up the battery positive electrode material in the sagger body 4, which facilitates the subsequent sifting operation. Specific Implementation Example 2

[0032] Please see Figure 1 , 2 5, 6, 7. Based on the first specific embodiment, the connecting plate 304 is fixed to the bottom of the fixed housing 1, and the two short sides of the top of the limiting platform 3 are fixed with mounting plates 301. The mounting plates 301 rotatably connect the two rotating rods 302 inside the fixed housing 1.

[0033] Specifically, two rotating rods 302 are rotatably connected to the upper part of the two mounting plates 301 on their adjacent sides. Support wheels 303 are fixed at both ends of the rotating rods 302. When the mounting plates 301 are working, the rotating rods 302 are connected to the support wheels 303. The support wheels 303 move in the conveying sagger body 4 in coordination with the driving wheel 104 and the driven wheel 102. The support wheels 303 rotate synchronously with the driving wheel 104 to ensure that the sagger body 4 is smoothly transferred to the sagger-turning station after cutting.

[0034] The operation process of this embodiment is as follows: During operation, when it is necessary to restrict the position of the sagger body 4 within the fixed outer shell 1, the electric push rod 305 is activated to drive the limiting platform 3 to rise. As the limiting platform 3 rises, the mounting plate 301 is also raised. When the sagger body 4 moves to contact the limiting platform 3 and the mounting plate 301, the position of the sagger body 4 is restricted. After the cutting and dispersing of the battery positive electrode material inside the sagger body 4 is completed, the electric push rod 305 is restarted to drive the limiting platform 3 to descend. When the limiting platform 3 descends to be supported on the connecting plate 304, the rotation of the drive wheel 104 drives the support wheel 303 to rotate until the sagger body 4 moves into the sagger-pouring device.
