Description

Technical Field

[0001] This utility model belongs to the field of lithium battery production technology and relates to a shaking device for producing lithium battery cathode materials. Background Technology

[0002] A lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. A lithium battery is a secondary battery composed of two compounds that can reversibly insert and extract lithium ions as positive and negative electrodes. That is, lithium in a lithium battery always appears in the form of lithium ions and never in the form of metallic lithium. The positive electrode material of a lithium battery must be roasted in a high-temperature kiln during the processing. The firing process requires the use of a sagger. Currently, the raw material powder of the positive electrode material is generally added to the sagger through a feeding device, then the material is shaken evenly, and finally sintered.

[0003] For example, patent CN220214698U discloses an automated shaking device for producing lithium battery cathode materials using saggers. This patent involves placing saggers containing lithium battery cathode material raw materials sequentially on the equipment base. Side uprights assist in arranging the saggers on the top surface of a movable long groove. Then, an electromagnet is connected to the circuit through a control system. The electromagnet and the vertical axis of the magnet have opposite magnetic properties, so the vertical axis of the magnet moves downward along the movable long groove under the action of magnetic attraction. At this time, the connecting spring is compressed, which drives the anti-leakage top plate to move downward. The anti-leakage top plate makes contact with the top surface of the sagger, keeping the sagger sealed and preventing the lithium battery cathode material raw materials inside the sagger from leaking out during the movement of the sagger.

[0004] When using the above technology, the following technical problems were found in the existing technology: During use, the saggers need to be placed on the equipment one by one, shaken, and then removed. Each sagger needs to be placed, shaken, and removed individually. This process is repeated, which increases the complexity of the operation. The method of processing the saggers one by one limits the processing capacity of the shaking equipment, resulting in low overall shaking efficiency. This not only affects the production progress but may also increase the production cost.

[0005] The technical problem this invention aims to solve is that during the use of the shaking equipment, it is necessary to place each sagger on the equipment one by one, shake it, and then remove it. Each sagger needs to be placed, shaken, and removed individually. This process is repeated, which increases the complexity of the operation. The method of processing the sagger one by one limits the processing capacity of the shaking equipment, resulting in low overall shaking efficiency. This not only affects the production progress but may also increase production costs.

[0006] This utility model discloses a shaking device for producing lithium battery cathode materials, comprising a mounting support frame, a roller conveyor belt mounted at the bottom of the mounting support frame, a sliding frame slidably connected to the top of the mounting support frame, a clamping assembly connected to the bottom of the sliding frame, two connecting plates mounted on both sides of the mounting support frame, an electric telescopic rod mounted on the connecting plates, a connecting frame mounted at the end of the electric telescopic rod away from the connecting plates, and a guiding assembly mounted on the roller conveyor belt; the clamping assembly includes a clamping mounting frame and a lead screw, the bottom of the sliding frame mounted on the top of the clamping mounting frame, the bottoms of the two connecting frames mounted on the same clamping mounting frame, the lead screw rotatably connected to the clamping mounting frame, and a first servo motor connected to one end of the lead screw.

[0007] Two drive blocks are threaded onto the lead screw, and a clamping rod is mounted on the drive block; a clamping plate is mounted on the clamping rod, the clamping rod is L-shaped, an upper clamping component is provided on the clamping rod, and a rubber anti-slip pad is mounted on the clamping plate.

[0008] The upper clamping component includes a sliding ring, which is slidably connected to the clamping rod. An upper clamping plate is installed on the sliding ring, and a fixing bolt is threaded onto the sliding ring.

[0009] The guiding assembly includes a first fixing plate and an electric push rod. There are two first fixing plates, which are installed on both sides of the roller transmission belt. A first pin bracket is installed on the first fixing plate, and a connecting shaft is hinged to the first pin bracket.

[0010] A guide plate is connected to the connecting shaft, and two second pin brackets are hinged to both ends of the electric push rod. The two second pin brackets are respectively installed on the first fixed plate and the guide plate.

[0011] Two support bases are installed at the bottom of the roller conveyor belt, and a motor mounting bracket is installed on the first servo motor. The first servo motor is mounted on the clamping mounting bracket through the motor mounting bracket.

[0012] Compared with existing technologies, the advantages of this invention are as follows: The automatic clamping, shaking, and conveying of the saggers are achieved through the cooperation of the electric telescopic rod, servo motor, and roller conveyor belt, greatly reducing manual operation and improving production efficiency. The rotation of the lead screw driven by the first servo motor allows for precise control of the clamping rod's movement distance and speed, ensuring stable clamping and shaking of the saggers and reducing uneven distribution of battery materials caused by uneven shaking. The automated system significantly reduces manual operation, lowering the labor intensity of workers and minimizing errors and malfunctions caused by human factors. By adjusting the control parameters of the first servo motor, it can easily adapt to saggers of different sizes and shapes, making the device widely applicable. Attached Figure Description

[0019] Example 1

[0020] like Figures 1-5 As shown, the system includes a mounting support frame 1, a roller conveyor belt 2 mounted on the bottom of the mounting support frame 1, a sliding frame 3 slidably connected to the top of the mounting support frame 1, a clamping assembly connected to the bottom of the sliding frame 3, two connecting plates 4 mounted on both sides of the mounting support frame 1, an electric telescopic rod 5 mounted on the connecting plate 4, a connecting frame 6 mounted on the end of the electric telescopic rod 5 away from the connecting plate 4, and a guide assembly mounted on the roller conveyor belt 2; the clamping assembly includes a clamping mounting frame 71 and a lead screw 72, the bottom of the sliding frame 3 is mounted on the top of the clamping mounting frame 71, the bottoms of the two connecting frames 6 are mounted on the same clamping mounting frame 71, the lead screw 72 is rotatably connected to the clamping mounting frame 71, and one end of the lead screw 72 is connected to a first servo motor 73;

[0021] During operation, the roller conveyor belt 2 transports the crucible filled with battery material to the clamping rod 75 on the clamping assembly. Then, the first servo motor 73 starts, driving the lead screw 72 connected to it to rotate. The lead screw 72 rotates on the mounting support frame 1, driving the drive block 74 threaded to it to move horizontally on the lead screw 72. In turn, the drive block 74 drives the clamping rod 75 connected to it to move to both sides of the crucible, so that the two clamping plates 76 and the clamping plate 76 connected to them come closer to each other to clamp the crucible. After the crucible is clamped and fixed, the electric telescopic rod 5 drives the clamping mounting frame 71 on the clamping assembly to slide horizontally on the mounting support frame 1 through the sliding frame 3. The two electric telescopic rods 5 drive the clamping mounting frame 71 to move the clamped and fixed crucible horizontally left and right, and then shake the crucible left and right to shake the battery material in the crucible evenly. After shaking, the crucible is released and conveyed to the next process by the roller conveyor belt 2, and then the next crucible that needs to be shaken is shaken.

[0022] By coordinating the electric telescopic rod 5, servo motor, and roller conveyor belt 2, the automatic clamping, shaking, and conveying of the crucibles are achieved, greatly reducing manual operation and improving production efficiency. The first servo motor 73 drives the lead screw 72 to rotate, precisely controlling the movement distance and speed of the clamping rod 75, thus ensuring the crucibles are stably clamped and shaken, reducing uneven distribution of battery materials caused by uneven shaking. This automated system significantly reduces manual operation, lowers the labor intensity of workers, and also reduces errors and malfunctions caused by human factors.

[0023] Example 2

[0024] like Figure 2 , Figure 3 and Figure 5 Two drive blocks 74 are threadedly connected to the lead screw 72, and clamping rods 75 are mounted on the drive blocks 74. A clamping plate 76 is mounted on the clamping rods 75. The clamping rods 75 are L-shaped and have an upper clamping component. A rubber anti-slip pad 10 is mounted on the clamping plate 76. By adding the rubber anti-slip pad 10, the contact area between the clamping plate 76 and the crucible is increased, thereby improving the clamping stability. During operation, the first servo motor 73 starts and drives the lead screw 72 connected to it to rotate. The rotation of the lead screw 72 on the mounting support frame 1 drives the drive blocks 74 threaded to it to move horizontally on the lead screw 72. In turn, the drive blocks 74 drive the clamping rods 75 and the clamping plate 76 connected to them to move to both sides of the crucible to clamp both sides of the crucible and fix the crucible. By adjusting the control parameters of the first servo motor 73, it can easily adapt to crucibles of different sizes and shapes, which makes the device widely applicable.

[0025] Example 3

[0026] like Figure 2 and Figure 5 The upper clamping component includes a sliding ring 771, which is slidably connected to the clamping rod 75. An upper clamping plate 772 is mounted on the sliding ring 771, and a fixing bolt 773 is threaded onto the sliding ring 771. During operation, the fixing bolt 773 is loosened, allowing the sliding ring 771 to drive the upper clamping plate 772 to slide on the clamping rod 75. This allows the user to freely adjust the height of the upper clamping component according to the height of the crucible. The upper clamping plate 772 clamps the crucible by being driven by the clamping rod 75 on the clamping assembly, thus fixing the top of the crucible and improving its stability during shaking.

[0027] Example 4

[0028] like Figure 1 and Figure 4 The guiding assembly includes a first fixed plate 81 and an electric push rod 85. There are two first fixed plates 81, which are installed on both sides of the roller transmission belt. A first pin bracket 82 is installed on the first fixed plate 81. A connecting shaft 83 is hinged to the first pin bracket 82. A guiding plate 86 is connected to the connecting shaft 83. Two second pin brackets 84 are hinged to both ends of the electric push rod 85. The two second pin brackets 84 are respectively installed on the first fixed plate 81 and the guiding plate 86.

[0029] During operation, the electric push rod 85 pushes the guide plate 86 to rotate via the second pin brackets 84 at both ends. The guide plate 86 rotates at an angle via the connecting shaft 83 on the first pin bracket 82 on the first fixed plate 81. By adjusting the offset angle of the guide plate, the two guide plates 86 form a V-shape on the roller conveyor belt 2, so that the crucible is guided between the two guide plates 86, allowing the crucible to be transmitted at the center position of the roller conveyor belt 2, which facilitates the clamping plate 76 on the clamping assembly to clamp the crucible. The guide assembly keeps the crucible in the correct position and posture on the conveyor belt, thereby facilitating the clamping operation of the clamping plate 76 on the clamping assembly. The clamping plate 76 can clamp the crucible more easily and accurately, improving clamping efficiency and accuracy. By guiding and positioning the crucible through the guide assembly, problems such as clamping failure or transmission failure caused by incorrect crucible position can be reduced.

[0030] Example 5

[0031] like Figure 1 and Figure 3 Two support bases 9 are installed at the bottom of the roller conveyor belt 2. A motor mounting bracket 11 is installed on the first servo motor 73. The first servo motor 73 is mounted on the clamping mounting bracket 71 through the motor mounting bracket 11. During operation, the motor mounting bracket 11 is used to install and fix the first servo motor 73. The first servo motor 73 is mounted on the clamping mounting bracket through the bolts on the motor mounting bracket 11.

[0032] The operation of the shaking device for producing lithium battery cathode materials provided by this utility model is as follows: During operation, the roller conveyor belt 2 transports the cassette filled with battery materials to the clamping rod 75 on the clamping assembly. Then, the first servo motor 73 starts, driving the lead screw 72 connected to it to rotate. The lead screw 72 rotates on the mounting support frame 1, driving the drive block 74 threaded to it to move horizontally on the lead screw 72. In turn, the drive block 74 drives the clamping rod 75 connected to it to move to both sides of the cassette, so that the two clamping plates 76 and the clamping plates 76 connected to them move closer to each other to clamp the cassette and fix it. After the sagger is fixed, the electric telescopic rod 5 drives the clamping mounting frame 71 on the clamping assembly to slide horizontally on the mounting support frame 1 via the sliding frame 3. The two electric telescopic rods 5 drive the clamping mounting frame 71 to move the clamped sagger horizontally left and right, thereby shaking the sagger left and right to even out the battery material in the sagger. After shaking, the sagger is released and conveyed to the next process by the roller conveyor belt 2, and then the next sagger that needs to be shaken is shaken. Through the cooperation of the electric telescopic rod 5, the servo motor and the roller conveyor belt 2, the automatic clamping, shaking and conveying of the sagger is realized, which greatly reduces manual operation and improves production efficiency.

[0033] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
