Description

Technical Field

[0001] This invention relates to the field of battery cell assembly and pairing technology, and more particularly to a battery cell air pairing and assembly mechanism. Background Technology

[0002] With the widespread use of portable electronic devices such as smartphones and tablets, consumers have placed higher demands on the battery life of these devices. To meet market demand, dual-cell solutions are widely used in various digital products due to their ability to provide higher charging power and faster charging speeds. In the production process of dual-cell batteries, the assembly and pairing of the cells is a crucial step. Traditional cell assembly and pairing typically employs a single-machine automated production mode, where cells need to be removed from the production line, assembled at a separate pairing station, and then returned to the production line. This offline pairing method has many drawbacks.

[0003] First, offline pairing requires additional handling modules and complex positioning mechanisms, resulting in bulky equipment, occupying significant production space, and increasing production costs and maintenance difficulty. Second, errors can easily occur during the handling and positioning of battery cells between different workstations, affecting pairing accuracy and product yield. Furthermore, offline pairing increases production cycle time and reduces overall production efficiency. More importantly, without the battery cells leaving the circular conveyor line, the aerial pairing of two cells must not disrupt the continued transport and processing of other vehicles on the circular line. This makes it difficult for existing technologies to achieve efficient and accurate aerial pairing of battery cells while ensuring production continuity. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0004] This invention discloses an aerial pairing and assembly mechanism for battery cells, which aims to solve the problems of large equipment size, low pairing accuracy, low production efficiency, and difficulty in achieving efficient and accurate aerial pairing and assembly of battery cells without affecting the continuity of the circular conveyor production line in traditional battery cell pairing and assembly methods.

[0005] The technical solution of the present invention is as follows:

[0006] A battery cell over-the-air pairing and assembly mechanism, comprising:

[0007] Servo handling module, used to drive the air pairing and assembly mechanism of battery cells to move along the conveying direction of the circular conveying track;

[0008] Lifting cylinder, connected to servo handling module;

[0009] A fixed side suction plate is connected to a lifting cylinder to clamp a battery cell;

[0010] A movable side suction plate, connected to a lifting cylinder, is used to clamp another battery cell; and a servo cylinder is used to drive the movable side suction plate to move relative to the fixed side suction plate so that the two battery cells fit together.

[0011] This technical solution enables the aerial combination and pairing of battery cells without affecting the continuity of the circular conveyor production line, effectively solving the problems of large equipment size, low pairing accuracy, and low production efficiency caused by traditional offline pairing methods.

[0012] Furthermore, the battery cell air pairing and assembly mechanism also includes a telescopic cylinder connected to the fixed side suction plate and an alignment push block connected to the telescopic cylinder; the telescopic cylinder is used to drive the alignment push block to move so that the ends of the two battery cells are aligned.

[0013] This technical solution can further improve the accuracy of cell pairing, ensuring that the ends of the two cells are aligned, thereby improving product yield.

[0014] More specifically, in some implementations, the output of the servo electric cylinder is connected to the movable side suction plate.

[0015] This technical solution enables the servo electric cylinder to directly drive the movable side suction plate, resulting in a compact structure and fast response speed.

[0016] Preferably, the cylinder body of the servo electric cylinder is connected to the lifting cylinder.

[0017] This technical solution allows the servo electric cylinder to be stably fixed on the lifting cylinder, ensuring smooth and precise movement.

[0018] In some implementations, the movable side suction plate is arranged opposite to the fixed side suction plate.

[0019] This technical solution allows for easy clamping and bonding of two battery cells, resulting in a reasonable structural layout.

[0020] Preferably, the lifting cylinder is mounted on the servo handling module.

[0021] This technical solution enables the integration of lifting cylinders into a servo handling module, achieving overall movement and lifting functions.

[0022] More specifically, in some implementations, the lifting direction of the lifting cylinder is perpendicular to the conveying plane of the annular conveying track.

[0023] This technical solution enables precise vertical lifting and lowering of battery cells, facilitating aerial pairing operations.

[0024] Preferably, the direction of motion of the movable side suction plate driven by the servo electric cylinder is parallel to the conveying plane of the circular conveying track.

[0025] This technical solution enables precise horizontal bonding of battery cells, ensuring a tight fit.

[0026] In some implementations, a rubber plate is provided on the side of the alignment pusher facing the two cells.

[0027] This technical solution can avoid damage to the battery cell caused by the alignment pusher during the alignment process, while increasing friction and improving the stability of alignment.

[0028] Preferably, both the fixed side suction plate and the movable side suction plate are vacuum suction plates.

[0029] This technical solution enables the battery cell to be stably clamped by vacuum adsorption, preventing the battery cell from falling off or shifting during handling and pairing.

[0030] Beneficial Effects: The battery cell aerial pairing and assembly mechanism disclosed in this invention uses a servo-driven transport module to move the entire mechanism along a circular conveyor track, enabling battery cells to be paired without leaving the production line. A lifting cylinder connected to the servo-driven transport module is used to achieve vertical lifting of the mechanism, thereby completing the pairing operation in mid-air. Fixed and movable side suction plates are used to clamp two battery cells respectively. The servo-driven cylinder drives the movable side suction plate to move relative to the fixed side suction plate, causing the two battery cells to come into contact with each other.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] First, this invention employs an in-flight pairing method, avoiding the cumbersome process of traditional offline pairing, which requires removing battery cells from the production line, assembling them at an independent workstation, and then returning them to the production line. This significantly reduces additional handling modules and complex positioning mechanisms, thereby reducing equipment size, saving production space, and effectively lowering production costs and maintenance difficulty.

[0033] Secondly, since the battery cells remain on the circular conveyor track throughout the entire pairing process, the error in handling and positioning the battery cells between different workstations is reduced, thereby improving pairing accuracy and product yield.

[0034] Furthermore, the air pairing mode of the present invention allows the combination and pairing of battery cells to be carried out in parallel with the transportation and processing of other trolleys on the circular conveyor line, without affecting the production cycle and significantly improving the overall production efficiency.

[0035] More importantly, this invention achieves aerial pairing of two battery cells without the cells leaving the circular conveyor production line, and does not affect the continued transport and processing of other vehicles on the circular line. This solves the problem of existing technologies that struggle to achieve efficient and precise aerial pairing of battery cells while ensuring production continuity, providing a more efficient and precise solution for dual-cell production.

[0040] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0041] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] With societal development and the widespread adoption of mobile devices such as smartphones, users are increasingly demanding higher charging efficiency and speed. To meet market needs, dual-cell solutions are widely used in products such as smartphones and tablets. However, in the production process of pairing dual-cell A and B batteries, traditional production methods often require removing the cells from the circular conveyor line for off-line stand-alone production. This not only increases equipment footprint and reduces production efficiency but also increases the complexity of equipment maintenance and debugging, leading to increased production costs and energy consumption.

[0043] For example, suppose that on an automated production line, battery cell A and battery cell B are transported via a circular conveyor track 5. If a traditional off-line pairing method is used, battery cell A and battery cell B need to be removed from the circular conveyor track 5, transferred to a separate pairing station for assembly, and then placed back onto the conveyor line. This process is not only time-consuming but also requires additional handling modules and positioning mechanisms, making the entire production process lengthy and inefficient. Without addressing these issues, the production efficiency of dual-cell batteries will be difficult to improve, production costs will remain high, and the equipment will be bulky, hindering compact production line layouts and automation upgrades.

[0044] To address this issue, this application proposes an aerial cell pairing and assembly mechanism, aiming to solve the problems of low efficiency, high cost, and large space occupation in existing dual-cell pairing and assembly technologies. This mechanism achieves cell pairing and assembly directly in the air without removing the cells from the production line, thereby significantly improving equipment production efficiency and reducing manpower, space occupation, and costs.

[0045] This embodiment discloses a cell air-to-air pairing and assembly mechanism. See [link to documentation]. Figure 1 The system includes a servo handling module 1, a lifting cylinder 8, a fixed side suction plate 7, a movable side suction plate 3, and a servo electric cylinder 2. The servo handling module 1 drives the entire battery cell aerial pairing and assembly mechanism to move along the conveying direction of the circular conveying track 5, ensuring precise positioning and handling of the battery cells during transport. The lifting cylinder 8, connected to the servo handling module 1, enables the vertical lifting movement of the entire pairing mechanism, allowing for the gripping and placement of battery cells at different heights. The fixed side suction plate 7, connected to the lifting cylinder 8, holds one battery cell, while the movable side suction plate 3, also connected to the lifting cylinder 8, holds the other battery cell. The servo electric cylinder 2 drives the movable side suction plate 3 to move relative to the fixed side suction plate 7, causing the two battery cells to come into contact and complete the pairing.

[0046] Specifically, the servo handling module 1 can be a cantilevered servo drive system, precisely controlled by a servo motor, capable of high-speed, high-precision movement along the conveying direction of the circular conveyor track 5. The circular conveyor track 5 can be a closed-loop conveyor belt or chain system for continuous conveying of battery cells. The lifting cylinder 8 can be a single-acting or double-acting cylinder, controlling its extension and retraction via air pressure to achieve the vertical lifting of the fixed side suction plate 7 and the movable side suction plate 3. The fixed side suction plate 7 and the movable side suction plate 3 typically employ vacuum suction cups, using negative pressure to adsorb the battery cells, ensuring stable clamping of the battery cells during handling and pairing. The servo cylinder 2 can be a linear servo cylinder, its output end connected to the movable side suction plate 3, driving the movable side suction plate 3 to move precisely in the horizontal direction via a servo motor, thereby achieving the bonding of the two battery cells.

[0047] In actual operation, when battery cell A and battery cell B are transported to the designated position via the circular conveyor track 5, the servo handling module 1 drives the entire battery cell aerial pairing and assembly mechanism to move to the corresponding position. Then, the lifting cylinder 8 extends, causing the fixed side suction plate 7 and the movable side suction plate 3 to descend and pick up battery cell A and battery cell B respectively. After picking up, the lifting cylinder 8 retracts, lifting the two battery cells into the air. At this time, the servo cylinder 2 starts working, driving the movable side suction plate 3 to move closer to the fixed side suction plate 7, so that battery cell A and battery cell B fit together. During the fitting process, the precise control of the servo cylinder 2 ensures the alignment and tight bonding of the battery cells. After pairing is completed, the lifting cylinder 8 extends again, placing the assembled dual battery cells back into the carrier on the circular conveyor track 5, and then the servo handling module 1 continues to move to the next workstation.

[0048] Compared to existing technologies that require removing battery cells from the conveyor line for pairing, the air-pairing battery cell pairing and assembly mechanism of this embodiment has significant advantages. First, by completing pairing in the air, secondary handling and positioning of the battery cells are avoided, greatly simplifying the production process and improving production efficiency. Second, since the pairing process is directly integrated into the conveyor line, the need for additional handling modules and pairing mechanisms is reduced, thereby lowering equipment costs and floor space. Furthermore, the precise control of the servo handling module 1 and the servo electric cylinder 2 ensures the accuracy and quality of battery cell pairing, reducing the defect rate.

[0049] In summary, the air-pairing and combining mechanism for battery cells in this embodiment achieves air-pairing and combining of battery cells without leaving the circular conveying track 5 through the coordinated operation of the servo handling module 1, the lifting cylinder 8, the fixed side suction plate 7, the movable side suction plate 3, and the servo cylinder 2. The servo handling module 1 is responsible for the overall movement of the mechanism, the lifting cylinder 8 is responsible for the vertical gripping and placement of the battery cells, the fixed side suction plate 7 and the movable side suction plate 3 are responsible for the stable clamping of the battery cells, and the servo cylinder 2 precisely controls the movement of the movable side suction plate 3, ensuring a tight fit between the two battery cells. This series of operations not only improves production efficiency and reduces production costs, but also makes the equipment structure more compact and occupies less space, providing an efficient and economical solution for the automated production of dual-cell batteries.

[0050] In some embodiments of this application, the battery cell pairing and assembly mainly involves clamping the battery cells together using a fixed side suction plate 7 and a movable side suction plate 3. However, in actual operation, relying solely on the clamping of the suction plates is insufficient to ensure precise alignment of the ends of the two battery cells, which may lead to deviations in subsequent assembly and affect the overall performance and safety of the battery pack. To address this issue, this application further proposes an air-pairing and assembly mechanism for battery cells, which includes a telescopic cylinder 10 connected to the fixed side suction plate 7 and an alignment push block 9 connected to the telescopic cylinder 10. The telescopic cylinder 10 drives the alignment push block 9 to move, thereby aligning the ends of the two battery cells.

[0051] The telescopic cylinder 10 is an actuator that can achieve telescopic movement by air pressure. It is configured to precisely control the displacement of the alignment push block 9. The alignment push block 9 is usually made of a material with a certain degree of hardness and wear resistance. Its function is to apply a pushing force to the end of the battery cell during the battery cell bonding process, so that it can achieve precise alignment in the horizontal direction.

[0052] This application's solution introduces a telescopic cylinder 10 and an alignment pusher 9, enabling active alignment of the ends of two battery cells during the cell pairing and assembly mechanism. Specifically, after the fixed side suction plate 7 and the movable side suction plate 3 clamp the two battery cells and initially align them, the telescopic cylinder 10 is driven, causing the alignment pusher 9 to move towards the ends of the battery cells. After the alignment pusher 9 contacts the ends of the battery cells, its thrust adjusts the ends of the battery cells to the same horizontal line, thereby ensuring precise alignment of the ends of the two battery cells. This process effectively compensates for the shortcomings of relying solely on suction plates for cell alignment, significantly improving the accuracy of battery cell assembly.

[0053] Through the above technical solution, this application can effectively solve the problem of insufficient alignment accuracy of the battery cell ends in the prior art. The combined use of the telescopic cylinder 10 and the alignment pusher 9 enables not only rapid bonding of the battery cells during the air pairing and assembly process, but also ensures precise alignment of the battery cell ends, thereby improving the quality and efficiency of battery cell assembly, providing high-precision semi-finished products for subsequent battery pack assembly, and thus improving the overall performance and reliability of the battery pack.

[0054] In some preferred embodiments, the battery cell aerial pairing and assembly mechanism moves to a preset position driven by the servo handling module 1. Subsequently, the lifting cylinder 8 descends, allowing the fixed side suction plate 7 and the movable side suction plate 3 to respectively pick up two battery cells to be paired. After the battery cells are picked up and lifted into the air, the servo cylinder 2 drives the movable side suction plate 3 to move towards the fixed side suction plate 7, causing the two battery cells to come into contact with each other. During this process, to ensure precise alignment of the battery cell ends, the telescopic cylinder 10 is activated, driving the alignment push block 9 to extend from one side of the fixed side suction plate 7, gently contacting and pushing the ends of the two battery cells until they are fully aligned horizontally. Once the battery cells are properly attached and aligned, the lifting cylinder 8 descends, placing the paired battery cells onto the conveyor line for the next process. The telescopic cylinder 10 retracts the alignment push block 9, completing the entire pairing and assembly process.

[0055] In some embodiments described above in this application, the battery cell aerial pairing and assembly mechanism drives the movable side suction plate 3 to move relative to the fixed side suction plate 7 via the servo electric cylinder 2, so that the two battery cells are brought into contact with each other. However, the basic scheme does not explicitly specify the connection method between the servo electric cylinder 2 and the movable side suction plate 3, which may affect the movement accuracy and stability of the movable side suction plate 3 in practical applications, thereby affecting the bonding effect of the battery cells. Therefore, this application further proposes a scheme in which the output end of the servo electric cylinder 2 is connected to the movable side suction plate 3, aiming to ensure the precise movement of the movable side suction plate 3 through a more direct and stable connection method, thereby improving the bonding quality of the battery cells.

[0056] The output end of the servo cylinder 2 refers to the part of the servo cylinder 2 that directly generates linear or rotary motion, typically its piston rod or rotating shaft. Connecting this output end directly to the movable side suction plate 3 means that the power output of the servo cylinder 2 can be directly and efficiently transmitted to the movable side suction plate 3, reducing potential errors and energy losses from intermediate transmission links. The movable side suction plate 3 is a component used to clamp the battery cell, and the precision of its movement is crucial for the accurate bonding of the battery cell.

[0057] The solution in this application directly connects the output end of the servo cylinder 2 to the movable side suction plate 3, allowing the precise displacement generated by the servo cylinder 2 to directly act on the movable side suction plate 3. This direct connection method effectively avoids problems such as transmission gaps, elastic deformation, or loose connections that may exist in traditional indirect connection methods, thereby ensuring that the motion trajectory and displacement of the movable side suction plate 3 driven by the servo cylinder 2 are highly consistent with the preset value. It is precisely because of this high-precision motion control that the two battery cells can achieve more precise alignment and tighter contact during the mutual bonding process, significantly improving the quality and efficiency of battery cell pairing and assembly.

[0058] Through the above technical solution, since the output end of the servo electric cylinder 2 is directly connected to the movable side suction plate 3, the number of links in the transmission chain is reduced, thereby effectively reducing the accumulation of motion errors and improving the accuracy and response speed of the movable side suction plate 3. This direct drive method enables the battery cells to achieve more precise positioning and more stable contact during the bonding process, significantly improving the quality and reliability of battery cell pairing and avoiding problems such as poor bonding or low efficiency caused by improper connection.

[0059] In some preferred embodiments, the servo cylinder 2 can be a linear servo cylinder, with its piston rod serving as the output end. This piston rod is directly fixed to the center of the back of the movable side suction plate 3 via a threaded connection, pin connection, or flange connection. This direct and rigid connection method ensures that the driving force of the servo cylinder 2 can be efficiently and without damage transmitted to the movable side suction plate 3, further guaranteeing the stability and accuracy of the battery cell bonding process.

[0060] In some embodiments of this application, the installation position of the servo electric cylinder 2 may affect the compactness and stability of the entire mechanism. Therefore, this application proposes connecting the cylinder body of the servo electric cylinder 2 to the lifting cylinder 8, thereby optimizing the structural layout and improving the overall performance of the mechanism.

[0061] Among them, the servo electric cylinder 2 is an actuator capable of precise position control. By receiving control signals, it drives its output end to generate linear motion. The lifting cylinder 8 is used to realize the vertical lifting of the fixed side suction plate 7 and the movable side suction plate 3, so as to facilitate the picking and placing of the battery cells.

[0062] By fixing the cylinder body of the servo cylinder 2 to the lifting cylinder 8, the impact of the servo cylinder 2's movement on other components can be reduced, improving system stability. Furthermore, this mounting method helps reduce the overall size of the mechanism, making it more compact. Because the cylinder body of the servo cylinder 2 is fixedly connected to the lifting cylinder 8, the reaction force of the servo cylinder 2's movement can be effectively absorbed by the lifting cylinder 8, thereby reducing vibration and noise and improving the smoothness of equipment operation.

[0063] This structure effectively utilizes space and reduces the overall size of the mechanism, making the battery cell pairing and assembly mechanism more compact. Simultaneously, by optimizing the installation position of the servo electric cylinder 2, the stability and reliability of the mechanism are improved, ensuring the accuracy and efficiency of battery cell pairing and assembly.

[0064] In some embodiments of this application, a servo-driven transport module 1 moves the battery cell aerial pairing and assembly mechanism along the conveying direction of the circular conveying track 5. A lifting cylinder 8 connects a fixed side suction plate 7 and a movable side suction plate 3 to clamp the battery cells. Finally, a servo cylinder 2 drives the movable side suction plate 3 to move, causing the two battery cells to come into contact with each other. However, in the above scheme, the positional relationship between the movable side suction plate 3 and the fixed side suction plate 7 directly affects the battery cell pairing efficiency and the overall performance of the mechanism. Therefore, this application proposes that the movable side suction plate 3 and the fixed side suction plate 7 be arranged opposite each other, which can effectively improve the accuracy and efficiency of battery cell pairing.

[0065] The movable side suction plate 3 and the fixed side suction plate 7 are arranged opposite each other, meaning that they are in a spatially facing state. Specifically, the clamping surfaces of the two side suction plates face each other to simultaneously clamp and fix two battery cells, thus facilitating subsequent pairing operations.

[0066] By positioning the movable side suction plate 3 opposite to the fixed side suction plate 7, it is ensured that the two battery cells maintain an optimal relative position during the pairing process. This structural design minimizes pairing failures caused by positional deviations, thereby improving overall pairing efficiency. Furthermore, the relative positioning simplifies the mechanism's control logic and reduces the complexity of the control system.

[0067] The structure of the movable side suction plate 3 and the fixed side suction plate 7 being arranged opposite each other can significantly improve the accuracy and efficiency of cell pairing, reduce the control difficulty, and thus improve the performance and reliability of the entire cell air pairing and assembly mechanism.

[0068] In some embodiments of this application, the specific installation position of the lifting cylinder 8 may affect the stability and space utilization of the entire mechanism. Therefore, this application proposes to mount the lifting cylinder 8 on the servo handling module 1, thereby optimizing the structural layout and improving the compactness and stability of the mechanism.

[0069] The servo handling module 1 serves as the moving carrier for the air-pairing and assembly mechanism of the battery cells, responsible for moving along the conveying direction of the circular conveying track 5. The lifting cylinder 8 drives the fixed side suction plate 7 and the movable side suction plate 3 to move up and down, thereby clamping and releasing the battery cells. By directly mounting the lifting cylinder 8 onto the servo handling module 1, intermediate connecting parts can be reduced, the structure simplified, and the overall rigidity improved.

[0070] The solution proposed in this application improves the compactness and stability of the mechanism because the lifting cylinder 8 is directly fixed to the servo handling module 1, shortening the force transmission path and reducing vibration and deformation caused by intermediate connecting parts. At the same time, this layout also lowers the center of gravity of the entire mechanism, further enhancing operational stability.

[0071] Through the above technical solutions, the structure of the cell air pairing and assembly mechanism is more compact and the operation is more stable, which can effectively improve the accuracy and efficiency of cell pairing.

[0072] In a preferred embodiment, the upper surface of the servo handling module 1 may be provided with mounting holes, and the bottom of the lifting cylinder 8 is fixed to the upper surface of the servo handling module 1 by bolts. This connection method is simple, reliable, and easy to install and maintain. In addition, to further improve the stability of the mechanism, a shock-absorbing pad can be added to the bottom of the lifting cylinder 8 to reduce the impact of vibration on the servo handling module 1.

[0073] In some embodiments of the battery cell air pairing and assembly mechanism of this application, the lifting direction of the lifting cylinder 8 is perpendicular to the conveying plane of the annular conveying track 5, thereby ensuring the precise adjustment of the battery cell in the vertical direction.

[0074] The lifting cylinder 8 is a pneumatic component capable of providing linear vertical movement. By controlling the air pressure, the extension and retraction of the lifting cylinder 8 can be precisely adjusted, thereby achieving vertical position adjustment of the fixed side suction plate 7 and the movable side suction plate 3. Specifically, the lifting direction of the lifting cylinder 8 is set perpendicular to the conveying plane of the annular conveying track 5, meaning that the movement trajectory of the lifting cylinder 8 forms a 90-degree angle with the plane of the annular conveying track 5. This vertical setting allows for precise vertical adjustment of the battery cells during the pairing and assembly process to meet the pairing requirements of battery cells of different specifications or sizes.

[0075] The reason why this application adopts a structure in which the lifting cylinder 8 is perpendicular to the conveying plane of the annular conveying track 5 is that when the battery cell moves on the annular conveying track 5, its horizontal position has already been precisely controlled by the servo handling module 1. In order to achieve precise pairing of the two battery cells, fine adjustment in the vertical direction is also required. By setting the lifting cylinder 8 to be perpendicular to the conveying plane of the annular conveying track 5, it can be ensured that the movement direction of the lifting cylinder 8 is consistent with the adjustment requirements of the battery cell in the vertical direction, thereby avoiding adjustment errors caused by inconsistent movement directions.

[0076] The above technical solutions ensure precise vertical adjustment of the battery cells, improving the accuracy and efficiency of cell pairing. Furthermore, using pneumatic components as the lifting mechanism enables rapid and stable lifting movements, further enhancing production efficiency.

[0077] As a preferred embodiment, a lifting cylinder 8 with position feedback can be used. By monitoring the position information of the lifting cylinder 8 in real time, precise control of the position of the battery cell in the vertical direction can be achieved.

[0078] In some embodiments of this application, the movement direction of the servo electric cylinder 2 driving the movable side suction plate 3 may not be parallel to the conveying plane of the annular conveying track 5, resulting in additional torsional force on the battery cells during the bonding process, affecting the pairing accuracy and efficiency. To address this, this application proposes a scheme where the movement direction of the servo electric cylinder 2 driving the movable side suction plate 3 is parallel to the conveying plane of the annular conveying track 5. By precisely controlling the movement trajectory of the movable side suction plate 3, the stable and accurate bonding of the battery cells is ensured.

[0079] Among them, the servo electric cylinder 2 is an actuator capable of precisely controlling displacement and speed. By receiving control signals, it drives the movable side suction plate 3 to move along a predetermined trajectory. The circular conveyor track 5 provides a continuous motion platform for the battery cell aerial pairing and assembly mechanism, enabling the battery cells to sequentially complete processes such as picking up, aligning, and bonding.

[0080] The solution proposed in this application effectively prevents the battery cells from tilting or twisting during the bonding process by aligning the movement direction of the movable side suction plate 3 driven by the servo cylinder 2 with the conveying plane of the annular conveying track 5, ensuring that the two battery cells can bond with each other in the best posture. Specifically, when the servo handling module 1 drives the battery cell aerial pairing and assembly mechanism to move along the annular conveying track 5, the servo cylinder 2, according to the control command, drives the movable side suction plate 3 to move in a direction parallel to the conveying plane of the annular conveying track 5, thereby achieving precise alignment and bonding of the two battery cells.

[0081] The above technical solution effectively improves the accuracy and efficiency of cell pairing, reduces the generation of defective products, and ensures the stability and reliability of the cell assembly mechanism. Compared with existing technologies, the solution proposed in this application can better adapt to the needs of high-speed and high-precision production, improve production efficiency, and reduce production costs.

[0082] As a preferred embodiment, the installation angle of the servo cylinder 2 can be adjusted so that the movement direction of its output shaft is strictly parallel to the conveying plane of the circular conveying track 5. Simultaneously, by adding sensors and control algorithms, the movement posture of the movable side suction plate 3 can be monitored in real time and adjusted according to actual conditions, thereby further improving the accuracy and stability of cell pairing.

[0083] In some embodiments of this application, the servo handling module 1 drives the air-pairing and assembly mechanism of the battery cells to move along the conveying direction of the circular conveying track 5, and the lifting cylinder 8 drives the fixed side suction plate 7 and the movable side suction plate 3 to clamp the battery cells. Then, the servo cylinder 2 drives the movable side suction plate 3 to move so that the two battery cells are in contact with each other. However, in actual operation, there may be slight misalignment at the ends of the battery cells, which will affect the subsequent process flow. In response, this application proposes an improvement scheme, namely, that the alignment push block 9 is provided with a rubber plate on one side facing the two battery cells. Through the elastic deformation of the rubber plate, damage to the battery cells can be effectively avoided, and the quality of the battery cells can be guaranteed.

[0084] The alignment pusher 9 is a structural component used to push the ends of the battery cells to align them. The rubber sheet, a flexible material, is disposed on the side of the alignment pusher 9 that contacts the battery cell. Specifically, the rubber sheet can be made of natural rubber, synthetic rubber, or silicone rubber, and its thickness and hardness can be selected according to actual needs. In a preferred embodiment, the rubber sheet can be fixed to the alignment pusher 9 by means of adhesive bonding, bolting, or snap-fit.

[0085] The solution in this application involves placing a rubber plate on the alignment pusher block 9. Utilizing the elasticity of the rubber, even slight misalignment during the alignment process of the battery cell ends can be buffered by the rubber plate, preventing hard impacts and damage to the battery cell. Simultaneously, the friction of the rubber plate increases the control force on the battery cell, making it easier to align.

[0086] The above technical solution effectively avoids damage to battery cells caused by hard impacts during alignment, improving the quality and reliability of cell pairing and assembly. Furthermore, the rubber plate reduces maintenance costs of the alignment mechanism and extends the equipment's lifespan.

[0087] In the battery cell air pairing and assembly mechanism of this application, the fixed side suction plate 7 and the movable side suction plate 3 are designed as vacuum suction plates. In this way, the battery cells can be clamped more reliably, ensuring the accuracy and stability of the pairing and assembly.

[0088] The vacuum suction plate refers to a device that uses the negative pressure generated by a vacuum to adsorb objects. Specifically, the surfaces of the fixed side suction plate 7 and the movable side suction plate 3 are provided with multiple tiny suction holes, which are connected to a vacuum pump through internal vacuum pipes. When the vacuum pump operates, the air around the suction holes is extracted, forming a negative pressure zone, thereby firmly adsorbing the battery cell onto the suction plate. As a preferred embodiment, the vacuum suction plate can be made of rubber or silicone with a certain degree of elasticity to increase the friction with the surface of the battery cell and improve the adsorption effect. In addition, the size and shape of the vacuum suction plate can be customized according to the size and shape of the battery cell to ensure the stability and reliability of the adsorption.

[0089] The solution proposed in this application, by employing vacuum suction plates as the fixed side suction plate 7 and the movable side suction plate 3, effectively solves the problem of battery cells easily slipping or shifting during clamping. Because the vacuum suction plates provide strong suction force, they ensure that the battery cells maintain a stable position during handling and pairing, thereby improving pairing accuracy and efficiency. Furthermore, the vacuum suction plates offer the advantage of non-destructive clamping, avoiding scratches or damage to the battery cell surface and ensuring the quality and performance of the battery cells.

[0090] Through the above technical solution, this application can achieve reliable clamping and stable handling of battery cells, thereby improving the accuracy and efficiency of battery cell pairing and assembly. Compared with traditional mechanical grippers, vacuum suction plates have better adaptability and versatility, and can be applied to battery cells of different sizes and shapes. In addition, vacuum suction plates also have the advantages of simple structure and easy maintenance, which can reduce equipment maintenance costs and downtime.

[0091] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
