Description

Technical Field

[0001] This utility model relates to the field of battery cell technology, and more specifically to a battery cell packaging device. Background Technology

[0002] Cell packaging equipment is a specialized device for packaging and sealing battery cells. It is widely used in the battery manufacturing industry, especially in lithium battery production.

[0003] The following problems exist in the market: The development of the new energy industry has led to a continuous increase in the demand for lithium battery cells. The automation level of existing production lines needs to be improved, and the number of cells that can be packaged at the same time also needs to be increased in order to meet the growing demand.

[0004] The technical problem to be solved by this utility model is to provide a battery cell packaging device with high automation performance. Utility Model Content

[0005] The technical problem this utility model addresses is: to provide a highly automated battery cell packaging device; the device is mainly mounted on a frame and includes the following functional modules: an aluminum-plastic film feeding and cutting device responsible for feeding and cutting the aluminum-plastic film into strips to ensure that the aluminum-plastic film meets the requirements of subsequent processing; an aluminum-plastic film punching device punching holes in the aluminum-plastic film to form a positioning structure for placing the battery cell; an aluminum-plastic film precision cutting device precisely trims the edges of the punched aluminum-plastic film to ensure packaging quality; a battery cell tab folding device folds the tabs of the battery cell to facilitate packaging and ensure the integrity of subsequent sealing; a battery cell sealing device accurately places the battery cell with folded tabs onto the aluminum-plastic film and seals it; a battery cell sealing and feeding device transports the battery cell with folded tabs to the battery cell sealing device for automated feeding; and a battery cell sealing and unloading device removes the packaged battery cell from the sealing device for automated unloading.

[0006] A battery cell packaging device for packaging battery cells with aluminum-plastic film includes a frame, on which are provided: an aluminum-plastic film feeding and cutting device for feeding and cutting the aluminum-plastic film into strips; an aluminum-plastic film punching device for punching holes in the aluminum-plastic film to place the battery cell; an aluminum-plastic film precision cutting device for precision cutting the edges of the punched aluminum-plastic film; a battery cell tab folding device for folding the battery cell tabs; a battery cell sealing device for placing the battery cell with folded tabs onto the aluminum-plastic film and sealing it; a battery cell sealing and feeding device for feeding the battery cell with folded tabs to the battery cell sealing device; and a battery cell sealing and unloading device for unloading the battery cell after it has been sealed by the battery cell sealing device.

[0007] Preferably, the aluminum-plastic film feeding and cutting device includes an aluminum-plastic film stand, with two aluminum-plastic film mounting rollers spaced apart at the front end of the stand; a motor belt mechanism for driving the two aluminum-plastic film mounting rollers to rotate at the rear end of the stand; a plurality of guide rollers for guiding the aluminum-plastic film at the front end of the stand; and a cutting mechanism for cutting the aluminum-plastic film into sections.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the battery cell packaging equipment of this utility model,

[0009] The aluminum-plastic film feeding and cutting device consists of an aluminum-plastic film support frame, which is the main structure of the entire equipment and provides support. Two aluminum-plastic film mounting rollers are located at the front of the frame for mounting the film. A motor and belt mechanism is installed at the rear of the frame to drive the rotation of the mounting rollers. The motor is connected to the rollers via a belt to control the feeding and tension of the aluminum-plastic film. Multiple guide rollers are located at the front of the frame to guide the movement of the film, ensuring smooth and stable operation. The cutting mechanism is one of the core components of the device, used for cutting and segmenting the aluminum-plastic film. The cutting mechanism can cut the film using blades or other methods to achieve the required size and shape.

[0010] The aluminum-plastic film punching device has a punching mechanism as its core functional component, responsible for punching holes in the aluminum-plastic film. The feeding mechanism is responsible for feeding the aluminum-plastic film, including a vertical feeding stand, a second linear module, and two moving mechanisms. This ensures the material can smoothly enter the punching station. The vertically mounted feeding stand is used to fix and support the aluminum-plastic film. The horizontally mounted second linear module drives the synchronous movement of the two moving mechanisms. The first and second moving mechanisms move synchronously with the second linear module. Specifically, the first moving mechanism moves the aluminum-plastic film to the pitch-changing mechanism, while the second moving mechanism conveys the pitch-changed aluminum-plastic film to the punching mechanism. The pitch-changing mechanism changes the spacing of the aluminum-plastic film during the feeding process, making its position more precise and facilitating the punching operation.

[0011] The aluminum-plastic film precision cutting device consists of a precision cutting mechanism responsible for accurately cutting the aluminum-plastic film to meet the requirements of fine processing; a material handling mechanism that can grasp multiple aluminum-plastic films, enabling batch processing and improving work efficiency; a pitch adjustment mechanism used to adjust the spacing between multiple aluminum-plastic films, ensuring that the distance between each film is suitable for the cutting operation before being fed into the precision cutting mechanism; a first transport mechanism that conveys the aluminum-plastic film after pitch adjustment to the precision cutting mechanism, ensuring the continuity of the entire operation process; and an output mechanism that delivers the precision-cut aluminum-plastic film for subsequent processing or packaging.

[0012] The battery cell tab leveling device includes an alignment mechanism to ensure accurate alignment of the battery cells before they enter the leveling device, preventing misalignment during subsequent processing. This mechanism may include mechanical positioning devices or sensors to automatically detect and adjust the cell's position. The leveling mechanism flattens the tab portion of the battery cell, ensuring its flatness in subsequent operations. Leveling can be performed through mechanical pressing, vibration, or other physical methods. An inspection mechanism checks the battery cell's condition after leveling to ensure its tab portion has reached the required standard. This mechanism may include a visual inspection system such as a camera and image processing technology to capture any defects or irregularities. A transport system moves the battery cells from the alignment mechanism to the leveling mechanism, and then from the leveled cells to the inspection mechanism. This system may include conveyor belts, robotic arms, or other automated equipment to ensure smooth and precise flow of the battery cells.

[0013] The battery cell tab folding device and the third transport mechanism are used to transport the battery cells from the loading area to the processing positions of each process. The tab folding mechanism folds the tabs on the battery cells to ensure that the shape of the tabs meets the requirements of subsequent processing. The flipping mechanism flips the folded battery cells to facilitate the subsequent tab flattening process. The flattening mechanism flattens the tabs of the flipped battery cells to ensure that the tab surface is flat and free from warping. The rotating mechanism rotates and adjusts the flattened battery cells to meet the directional requirements of subsequent unloading and other processes. The unloading conveyor belt transports the rotated and adjusted battery cells to the unloading area for collection or entry into the next process.

[0014] The battery cell sealing and feeding device consists of a feeding frame and a fifth linear module. The feeding frame provides support to ensure the stability of the entire system. The fifth linear module drives the third, fourth, and fifth sliders, enabling precise control of the position and movement trajectory of each operating part. The battery cell picking mechanism on the third slider is responsible for picking up the battery cells from the battery cell receiving line and placing them in the first buffer zone. The battery cell rotating mechanism can rotate the battery cells in the buffer zone and place them on the first conveyor line. To ensure the correct orientation of the battery cells and facilitate subsequent operations, it can meet the directional requirements of the battery cells, such as the joint position. The battery cell distributing mechanism on the fifth slider is responsible for distributing the battery cells on the first conveyor line to the second conveyor line. To handle the conveying process of multiple battery cells more efficiently, it ensures that the distributing mechanism can handle battery cells of different specifications and can handle a certain battery cell flow rate, avoiding jamming or misalignment.

[0015] The battery cell sealing device includes a first conveyor line and a second conveyor line arranged in parallel and at intervals. Each conveyor line is equipped with several battery cell film-coating carriers. The film-coating carriers are responsible for synchronous conveying and can fold aluminum-plastic film to cover the battery cells. The movement of the film-coating carriers is synchronized with the conveyor lines to achieve continuous operation. Above the first and second conveyor lines, there are multiple left sealing mechanisms and right sealing mechanisms respectively. The left sealing mechanism is used to seal the left side of the aluminum-plastic film, and the right sealing mechanism is used to seal the right side. The left and right sealing mechanisms are arranged at intervals to adapt to the movement rhythm of the battery cells. The device achieves continuous and efficient sealing operation through the two conveyor lines and the synchronously reciprocating carriers. The independent setting of the left and right sealing mechanisms ensures the flatness and firmness of the aluminum-plastic film seal. The device is suitable for mass production, reduces manual intervention, and improves production consistency.

[0016] The battery cell sealing and unloading device, a four-sided rotary table, provides the function of transferring battery cells between different processing stations. Several clamps are installed on the rotary table to fix the battery cells and bring them to the side sealing, short-circuit testing, and edge trimming stations, making the overall production line layout more compact and the conveying more efficient. The side sealing mechanism completes the edge sealing operation of the battery cells; heating and pressing are used to ensure a firm seal and improve the sealing performance of the battery cells. The short-circuit testing mechanism is responsible for short-circuit testing of the battery cells to ensure their safety before subsequent processing. The edge trimming mechanism trims the edges of the battery cells through cutting or punching to ensure that their dimensions meet requirements and removes excess material. The feeding mechanism provides the battery cells to be processed to the four-sided rotary table mechanism. The unloading mechanism removes the processed battery cells from the four-sided rotary table mechanism and transports them to the next process or collection area.
