Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically to a lithium battery flipping and feeding device. Background Technology

[0002] Against the backdrop of the rapid development of the new energy industry, lithium batteries, as core components in electric vehicles, energy storage systems, and consumer electronics, are experiencing continuous increases in production scale and technological requirements. The manufacturing process of lithium batteries involves multiple precision steps, including electrode preparation, cell assembly, electrolyte injection, packaging, and testing. Among these, cell flipping and feeding are key processes throughout the production process. For example, in steps such as electrode stacking, cell casing, and module assembly, the cells must be flipped at a specific angle and precisely transported to the next workstation.

[0003] Existing lithium battery flipping devices have limitations in practical applications and cannot be adapted to different types of lithium batteries. Downtime for replacing equipment parts and readjusting parameters would severely disrupt production, resulting in low practicality of the device.

[0004] According to the authorization announcement number CN 220617384 U, a flipping device for lithium battery production is disclosed, including a workbench. A control box is provided on the top left side of the workbench, and a fixed bracket is fixedly connected to the top center of the workbench. A motor is provided on the top of the workbench, and a conveyor belt is connected to the output end of the motor. A base plate is connected to the top of the fixed bracket, and side plates are connected to the top left and right sides of the base plate. A rotating shaft is connected to the center of the side plate, and a handle is connected to the left end of the rotating shaft. A connecting plate is connected to the right end of the rotating shaft.

[0005] The aforementioned patents confirm that lithium battery flipping devices have limitations in practical applications, failing to adapt to different types of lithium batteries, resulting in low practicality. Therefore, a new lithium battery flipping and feeding device is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a lithium battery flipping and feeding device, which uses a rotating block and a rotating cylinder to drive the lithium battery held in the middle of the clamping block to rotate and flip, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lithium battery flipping and feeding device includes a conveyor frame for conveying lithium batteries. Several sets of fixed frames are installed on the side wall of the conveyor frame. A rotating block is rotatably installed in the middle of each set of fixed frames. A flipping component for driving the lithium battery to flip is installed on the side of each set of rotating blocks.

[0009] The flipping assembly includes a rotary cylinder mounted on the side of the rotating block to drive the connecting block to rotate. One side of the connecting block is connected to the output end of the rotary cylinder. Two sets of clamping blocks are installed on the side wall of the connecting block to clamp the lithium battery. One set of clamping blocks is slidably mounted in the middle of the connecting block.

[0010] Preferably, each set of fixed frames is equipped with a servo motor that drives the rotating shaft to rotate on its side, and each set of rotating shafts is installed through the middle of the corresponding fixed frame and rotating block.

[0011] Preferably, each set of rotating shafts has several sets of locking blocks installed on the outer arc surface corresponding to the rotating block, and each set of rotating blocks has a locking groove in the middle that matches the locking block.

[0012] Preferably, each set of connecting blocks has a sliding groove on its side, and a slider that slides in accordance with the sliding groove is installed at one end of the clamping block.

[0013] Preferably, a stepper motor for driving the screw to rotate is installed on the other side of each set of connecting blocks, the screw of each set passes through the side wall of the connecting block and is installed inside the slide groove, and the slider of each set passes through and is installed in the middle of the screw.

[0014] Preferably, buffer pads are installed on the opposite surfaces of both sets of clamping blocks, and the surface of each set of buffer pads is provided with anti-slip texture.

[0015] Preferably, the upper part of the conveyor frame is equipped with several sets of limiting blocks corresponding to the fixed frame, and the upper part of each set of limiting blocks abuts against the lower surface of the corresponding rotating block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When lithium batteries need to be flipped on the conveyor surface, two sets of clamping blocks grip both sides of the battery. Then, a rotating block drives the clamped battery upwards, detaching it from the conveyor surface. Simultaneously, a rotary cylinder drives the connecting block and the lithium battery held in the center of the clamping blocks to rotate synchronously, thus completing the flipping action. By stably clamping the lithium battery with the clamping blocks, and coordinating the rotation with the rotary cylinder, the flipping operation is not only ensured, but the adjustable design of the clamping blocks also allows them to accommodate different battery models.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a lithium battery flipping and feeding device, such as... Figures 1-5 As shown, the device includes a conveyor frame 1 for transporting lithium batteries. Several sets of fixed frames 2 are mounted on the side walls of the conveyor frame 1. A rotating block 3 is rotatably mounted in the center of each set of fixed frames 2, and a flipping assembly 8 for rotating the lithium batteries is mounted on the side of each set of rotating blocks 3. The conveyor frame 1 uses an internal conveyor belt or roller structure to continuously transport lithium batteries within the device, providing a stable material supply for the subsequent flipping process. The fixed frames 2 provide mounting bases for the rotating blocks 3 and the flipping assemblies 8, allowing the flipping assemblies 8 to be fixed to the upper part of the conveyor frame 1. The rotating blocks 3 can rotate around their own axis, causing the flipping assemblies 8 mounted on their sides to adjust their angle, thereby causing the lithium batteries to detach from the surface of the conveyor frame 1. The flipping assemblies 8 are used to flip the lithium batteries that have detached from the surface of the conveyor frame 1.

[0026] The flipping assembly 8 includes a rotary cylinder 81 mounted on the side of the rotating block 3 to rotate the connecting block 82. One side of the connecting block 82 is connected to the output end of the rotary cylinder 81. Two sets of clamping blocks 83 are mounted on the side wall of the connecting block 82 to clamp the lithium battery. One set of clamping blocks 83 is slidably mounted in the middle of the connecting block 82. The rotary cylinder 81 can drive the connecting block 82 and its side components to flip, thereby causing the lithium battery clamped in the middle of the clamping block 83 to flip. One end of the connecting block 82 is connected to the output end of the rotary cylinder 81, which can transmit the rotational motion of the rotary cylinder 81 to the clamping block 83, thereby causing the lithium battery in the middle of the clamping block 83 to rotate. One set of clamping blocks 83 can slide in the middle of the connecting block 82. By moving and adjusting the clamping distance, the device can be adapted to lithium batteries of different sizes. When it is necessary to flip the lithium battery, the clamping block 83 first clamps the lithium battery, and then the rotating block 3 will drive its side flipping component 8 to rotate upward. At the same time, the rotating cylinder 81 drives the lithium battery in the middle of the clamping block 83 to flip. After the flipping is completed, the rotating block 3 rotates in the opposite direction to drive the lithium battery back to the surface of the conveyor frame 1.

[0027] The rotary cylinder 81 can be a rotary cylinder with a torque parameter of 1.5 N·m and a rotation angle of 180°. The torque of 1.5 N·m can ensure that the connecting block 82 and the clamping block 83 can be smoothly rotated to flip the lithium battery, while avoiding excessive torque from impacting the components; the 180° rotation angle meets the common flipping requirements of lithium batteries and adapts to the flipping action design of the device.

[0028] Preferably, each set of fixing brackets 2 is equipped with a servo motor 4 on its side, which drives the rotating shaft 5 to rotate. Each set of rotating shafts 5 is installed through the middle of the corresponding fixing bracket 2 and rotating block 3. The servo motor 4 drives the rotating block 3 to rotate along the axial direction of the rotating shaft 5 through the rotating shaft 5, thereby realizing the angle adjustment between the rotating block 3 and its side components. When the clamping block 83 clamps the lithium battery, the servo motor 4 is started according to the control signal, driving the rotating shaft 5 to rotate, which in turn drives the rotating block 3 and the side components to rotate, ensuring that there is enough space when the flipping assembly 8 flips the lithium battery, thus preparing for the lithium battery to flip.

[0029] The servo motor 4 can be a motor with a rated speed of 1500 r / min and a positioning accuracy of ±0.01°. The rotating block 3 needs to quickly and accurately drive the flipping component 8 to adjust the angle. The speed of 1500 r / min can achieve a fast response and reduce the feeding waiting time; the high-precision positioning of ±0.01° can ensure that the flipping component 8 is in the accurate position when it flips the lithium battery, avoiding the lithium battery from falling or colliding with other parts due to angle deviation.

[0030] Furthermore, each set of rotating shafts 5 has several sets of locking blocks 6 installed on the outer arc surface corresponding to the rotating block 3, and each set of rotating blocks 3 has a locking groove 7 in the middle that matches the locking block 6. The locking block 6 is used to cooperate with the locking groove 7 on the rotating block 3, so that the rotating block 3 can rotate with the rotating shaft 5, ensuring stable operation of the device. The locking block 6 is embedded in the locking groove 7 to form a mechanical lock, preventing the rotating block 3 from shifting or shaking during the lithium battery flipping process. This structural design improves the installation accuracy and stability of the rotating block 3 and the flipping assembly 8, ensures the accuracy of the lithium battery flipping angle, and avoids flipping errors caused by loose parts.

[0031] Furthermore, each set of connecting blocks 82 has a sliding groove 84 on its side, and a slider 85 that slides in conjunction with the sliding groove 84 is installed at one end of the corresponding clamping block 83. The sliding groove 84 provides a sliding track for the slider 85 on the side of one set of clamping blocks 83, allowing the clamping blocks 83 to adjust the clamping spacing. This sliding structure design enables the flipping assembly 8 to adapt to lithium batteries of different specifications, improving the versatility and flexibility of the device, and ensuring that lithium batteries of different sizes can be stably clamped and flipped.

[0032] It is worth noting that a stepper motor 86, which drives the screw 87 to rotate, is installed on the other side of each connecting block 82. Each screw 87 passes through the side wall of the connecting block 82 and is installed inside the slide groove 84, while each slider 85 is installed through the middle of the screw 87. The stepper motor 86 drives the rotation of the screw 87 to achieve precise positioning of the clamping block 83. The screw 87 is installed inside the slide groove 84, and its external thread engages with the threaded hole in the middle of the slider 85, converting the rotational motion of the stepper motor 86 into the linear motion of the slider 85, thereby driving the clamping block 83 to move. The operator can precisely adjust the position of the clamping block 83 by controlling the rotation angle of the stepper motor 86 to match the clamping spacing with the size of the lithium battery.

[0033] The stepper motor 86 can be a motor with a step angle of 1.8° and a holding torque of 0.8 N·m. The clamping block 83 needs to be precisely adjusted according to the size of the lithium battery. The 1.8° step angle, combined with the screw 87 drive, can achieve millimeter-level precise displacement control; the 0.8 N·m holding torque can prevent the screw 87 from backing up due to force after clamping the lithium battery, ensuring a stable clamping distance and avoiding the lithium battery from being affected by loose clamping during the flipping process.

[0034] Specifically, buffer pads 9 are installed on the opposite surfaces of both sets of clamping blocks 83, and the surface of each set of buffer pads 9 is provided with anti-slip texture. The buffer pads 9 are made of elastic material, and when clamping the lithium battery, they buffer the clamping force through their own deformation, preventing the clamping blocks 83 from causing hard compression damage to the lithium battery casing. The anti-slip texture increases the roughness of the contact surface, increases the friction between the buffer pad and the lithium battery, and prevents the lithium battery from sliding or falling off during clamping and flipping.

[0035] More specifically, several sets of limiting blocks 10 are installed on the upper part of the conveyor frame 1 corresponding to the fixed frame 2, and the upper part of each set of limiting blocks 10 abuts against the lower surface of the corresponding rotating block 3. The limiting blocks 10 are used to limit the rotation range of the rotating block 3, prevent it from rotating excessively and hitting the surface of the conveyor frame 1, and ensure the safety of the flipping assembly 8 and the lithium battery.

[0036] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
