Description

Technical Field

[0001] This utility model relates to the field of battery cell processing, and in particular to a low-friction battery cell return carrier. Background Technology

[0002] In the automated production process of lithium battery cells, the cells typically need to circulate on a conveyor belt using carriers to connect different processes. Currently, the commonly used return carriers are mostly flat-bottomed block structures that are placed directly on the conveyor belt surface and driven by sliding friction. This contact method has significant drawbacks: First, the sliding friction between the carrier and the conveyor belt is large, resulting in high load on the conveyor belt motor and increased energy consumption; second, long-term direct friction not only accelerates the wear of the carrier's bottom but also causes premature wear on the conveyor belt surface, shortening the equipment's lifespan; furthermore, it generates significant noise during operation, and the carrier is prone to jamming when subjected to lateral forces from the production line, affecting the smoothness of the return flow. Utility Model Content

[0003] The purpose of this invention is to provide a low-friction battery cell return carrier to solve the above-mentioned problems.

[0004] According to one aspect of the present invention, a low-friction battery cell return carrier is provided, comprising: a carrier body, wherein a plurality of limiting blocks are provided on the top of the carrier body, the plurality of limiting blocks enclosing and forming a receiving groove for accommodating the battery cell; and a plurality of bearings are rotatably connected to the bottom of the carrier body by means of pins for rolling contact with a conveyor belt.

[0005] In some embodiments, the bottom of the vehicle body is provided with a plurality of bearing grooves symmetrically, and a pin is inserted into each bearing groove, with the bearing sleeved on the pin.

[0006] In some embodiments, the number of bearings is two or four.

[0007] In some embodiments, the rolling direction of the bearing is the same as the forward direction of the conveyor belt.

[0008] In some embodiments, the bearing is a deep groove ball bearing or a needle roller bearing.

[0009] In some embodiments, at least one end of the pin is provided with an anti-disengagement structure to prevent it from dislodging from the bearing groove.

[0010] In some embodiments, the anti-detachment structure is a cotter pin, a snap ring, or a riveted shaft end.

[0011] In some embodiments, the limiting block is made of an insulating material, and its surface in contact with the battery cell is covered with an insulating buffer layer.

[0012] This application brings multiple significant benefits by setting a bearing at its bottom to replace traditional sliding friction with rolling friction:

[0013] 1. Minimal frictional resistance: The bearings and the conveyor belt are in rolling contact, which greatly reduces the running resistance of the vehicle, thereby reducing the load and energy consumption of the drive motor;

[0014] 2. Excellent wear resistance: It avoids direct scratching between the vehicle and the conveyor belt, effectively extending the service life of the vehicle itself and the expensive conveyor belt, and reducing maintenance costs;

[0015] 3. Smooth and stable operation: The bearing rolling direction is consistent with the conveyor belt forward direction, ensuring the smooth operation of the vehicle and reducing jamming and impact;

[0016] 4. Improved working environment: The noise generated by rolling friction is much lower than that of sliding friction, which helps to create a quieter production environment;

[0017] 5. Enhanced safety and compatibility: The limit block is made of insulating material or covered with an insulating buffer layer, which not only prevents the risk of short circuit in the battery cell, but also avoids scratches on the surface of the battery cell, thus improving product quality.

[0020] 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.

[0021] refer to Figures 1 to 2This application provides a low-friction battery cell return carrier, comprising: a carrier body 1, wherein a plurality of limiting blocks 2 are provided on the top of the carrier body 1, and the plurality of limiting blocks 2 surround to form a receiving groove 3 for accommodating the battery cells; and a plurality of bearings 5 ​​are rotatably connected to the bottom of the carrier body 1 via pins 4 for rolling contact with a conveyor belt. By replacing the sliding friction of traditional carriers with the rolling friction between the bearings 5 ​​and the conveyor belt, the running resistance is fundamentally and significantly reduced. This not only reduces the load and energy consumption of the drive motor, but also greatly reduces the wear on the bottom of the carrier and the surface of the conveyor belt, effectively extending the service life of the equipment, while also significantly reducing operating noise.

[0022] In some embodiments, the bottom of the vehicle body 1 is symmetrically provided with multiple bearing grooves 6, and a pin 4 passes through each bearing groove 6, with the bearing 5 sleeved on the pin 4. This structure provides a stable and reliable bearing 5 installation solution. The bearing grooves 6 can accurately position and effectively limit the bearing 5, preventing lateral movement during operation and ensuring the straightness and stability of the vehicle's operation. At the same time, this modular design also facilitates the replacement and maintenance of individual bearings 5 ​​or pins 4.

[0023] In some embodiments, the number of bearings 5 ​​is two or four. Using two or four bearings 5 ​​is a preferred embodiment, achieving an optimal balance between cost and performance while ensuring vehicle support balance and smooth operation. A symmetrical arrangement of four bearings 5 ​​provides excellent stability, while two bearings 5 ​​offer a simpler structure and lower cost, both effectively meeting the needs of different application scenarios.

[0024] In some embodiments, the rolling direction of the bearing 5 is aligned with the forward direction of the conveyor belt. Aligning the rolling direction of the bearing 5 with the forward direction of the conveyor belt ensures that the bearing 5 travels on the belt with minimal rolling resistance, thereby maximizing the advantages of rolling friction. This arrangement further reduces the resistance of the vehicle's operation, making it run more smoothly and efficiently, and avoids lateral friction and wear caused by misalignment of the bearing 5.

[0025] In some embodiments, the bearing 5 is a deep groove ball bearing or a needle roller bearing. Deep groove ball bearings are ideal for this application due to their high load-carrying capacity, low coefficient of friction, and high rotational speed. Needle roller bearings, on the other hand, provide a larger load-bearing area when radial space is limited, making them suitable for thin-profile designs with strict requirements on carrier thickness. The selection of these two standardized bearings 5 ​​ensures reliable performance and convenient procurement.

[0026] In some embodiments, at least one end of the pin 4 is provided with an anti-detachment structure to prevent it from coming out of the bearing groove 6. The anti-detachment structure is a key safety design, which can effectively prevent the pin 4 from accidentally coming out of the bearing groove 6 during long-term vibration and operation, thereby avoiding the risk of carrier jamming, conveyor belt wear, or even production line shutdown caused by the bearing 5 falling off, and greatly improving the reliability and safety of equipment operation.

[0027] In some implementations, the anti-detachment structure is a cotter pin, a retaining ring, or a riveted shaft end. Cotter pins and retaining rings are removable anti-detachment structures, facilitating subsequent maintenance and component replacement; while riveted shaft ends provide a permanent anti-detachment solution, requiring no maintenance after installation and offering high connection strength. All three methods are mature, standard, and low-cost processes, and can be flexibly selected according to production and maintenance strategies.

[0028] In some embodiments, the limiting block 2 is made of insulating material, and its surface in contact with the battery cell is covered with an insulating buffer layer. The insulating properties effectively prevent the risk of external short circuits to the battery cell, improving safety during the production process; secondly, the buffer layer (such as rubber or silicone) can prevent the hard limiting block 2 from directly scratching or bumping the surface of the battery cell, thus protecting the battery cell casing and helping to ensure the yield rate of the final product.

[0029] It is worth noting that conventional conveyor belt systems usually have baffles on both sides to prevent the carrier from slipping out during operation. The width of the carrier body 1 in this invention is adapted to the spacing between the baffles on both sides, so that the carrier body 1 can achieve smooth return with low friction using the bearings 5, while also being confined within the channel formed by the baffles to run smoothly. The combination of these two factors ensures the high efficiency and reliability of the cell return process.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
