Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to a fully automatic sealing line for lithium batteries. Background Art

[0002] Lithium battery is a type of battery that uses lithium metal or lithium compounds as positive and negative electrodes to transfer lithium ions during the charge and discharge process to store and release electrical energy. This battery is widely used in many fields due to its high energy density, long life and light weight, such as portable electronic devices, electric vehicles, energy storage systems, etc. Compared with traditional nickel-cadmium batteries or lead-acid batteries, lithium batteries have higher energy density and lower self-discharge rate, so they are more popular.

[0003] At present, there are the following problems in the market: the existing battery packaging processes need to be completed separately, each step requires manual participation, and the dependence on operators is high, resulting in increased labor costs, and the speed is relatively low, affecting the production efficiency of lithium batteries;

[0004] The utility model aims to solve the technical problem of providing a fully automatic wire sealing process and integrating various working procedures. Utility Model Content

[0005] The utility model aims to solve the technical problem of providing a fully automatic line sealing, integrating various processes, reducing dependence on manpower, and improving production efficiency; adopting an unwinding and cutting module to be responsible for unwinding and cutting the aluminum-plastic film, the aluminum-plastic film roll is released by an unwinding mechanism, and the cutting device accurately cuts according to a set length to obtain an aluminum-plastic film segment of appropriate length; the punching module performs punching processing on the cut aluminum-plastic film, and punches out a pit on the aluminum-plastic film through the punching mechanism for subsequent accommodation of electric cores; the precision cutting module further cuts the edges and corners of the aluminum-plastic film after the punching, so that the edges and corners are neat; the aluminum-plastic film is accurately cut by a cutting tool or a laser cutting device to ensure that the edges and corners are smooth and free of burrs; the battery cell feeding module is responsible for the automatic feeding of the battery cell, and the battery cell is automatically transported to a designated position to prepare for the subsequent packaging process; the hot pressing module performs hot pressing shaping on the fed battery cell, and a certain temperature is applied to the battery cell by the hot pressing device and pressure to make its shape more regular, which is convenient for subsequent packaging; the folding ear module folds the ear of the battery cell after hot pressing, and folds or adjusts the ear of the battery cell through the folding ear mechanism to meet the packaging requirements; the flipping and positioning module flips and positions the battery cell after the folded ear, and flips the battery cell to a suitable angle and accurately positions it through the flipping mechanism and positioning device, which provides convenience for subsequent packaging operations; the packaging ring track module takes a piece of precision-cut aluminum-plastic film and a flipped and positioned battery cell, places the battery cell into the pit of the aluminum-plastic film, and folds the aluminum-plastic film in half; the aluminum-plastic film and battery cell are automatically picked up, positioned and placed through the ring track conveyor belt or robotic arm, and the folding mechanism folds the aluminum-plastic film in half so that the battery cell is completely wrapped; the packaging module packages the edges and corners of the aluminum-plastic film where the battery cell has been placed, and firmly seals the edges and corners of the aluminum-plastic film through heat sealing, ultrasonic sealing or other packaging methods to form a complete lithium battery.

[0006] A fully automatic sealing line for lithium batteries comprises an aluminum-plastic film and a battery cell, and further comprises: an unwinding and cutting module for unwinding and cutting the aluminum-plastic film into a set length; a punching module for punching holes in the cut aluminum-plastic film to accommodate the battery cell; a precision cutting module for cutting the edges and corners of the aluminum-plastic film after punching the holes to obtain an aluminum-plastic film with neat edges and corners; a battery cell feeding module for feeding the battery cell to a designated place; a hot pressing module for hot pressing and shaping the fed battery cell; a tab folding module for folding the tabs of the hot pressed battery cell; a flipping and positioning module for flipping and positioning the battery cell after the tab folding; a packaging ring rail module for taking a piece of precision-cut aluminum-plastic film and a flipped and positioned battery cell, placing the battery cell in the hole of the aluminum-plastic film, and then folding the aluminum-plastic film in half; and a packaging module for packaging the edges and corners of the aluminum-plastic film where the battery cell has been placed.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] 1. By fixing the aluminum-plastic film to be cut front and back, the possibility of the aluminum-plastic film being offset during cutting can be reduced, and because the cutter is located between the pressing plate and the first supporting plate, the cutting position is provided for the cutter while the aluminum-plastic film to be cut is fixed front and back, the structure is compact and the process is smooth;

[0009] 2. Before the aluminum-plastic film on the unwinding roller is used up, the aluminum-plastic film portion before unwinding to the guide roller can be fixed to the second support plate through the abutment plate under the action of the third cylinder. At this time, the staff can cut and replace the remaining aluminum-plastic film on the unwinding roller, and then connect it with the aluminum-plastic film portion before unwinding to the guide roller, without having to re-arrange the new aluminum-plastic film portion, thereby improving production efficiency;

[0010] 3. During the conveying process, the rotating roller rotates under the driving action of the third motor to provide conveying power to the aluminum-plastic film, thereby completing the conveying of the aluminum-plastic film. At the same time, the abutting roller abuts against the aluminum-plastic film to guide and flatten the aluminum-plastic film.

[0011] 4. The slitting mechanism cuts the aluminum-plastic film into two parts; the conveying mechanism is responsible for conveying the cut aluminum-plastic film to the punching mechanism; the limiting mechanism ensures the accuracy and consistency of the punching during the punching process; the punching mechanism creates pits or grooves on the aluminum-plastic film, performs necessary processing on the film, and can punch two or more aluminum-plastic films at one time;

[0012] 5. The guide rail is used to support and guide the movement of other components; the bearing platform is used to bear the aluminum-plastic film; the first moving module and the second moving module are installed on the guide rail and are used to move along the direction of the guide rail during the cutting process, so as to adapt to aluminum-plastic films of different sizes; the cutting mechanism is installed on the first moving module and the second moving module to cut off the excess edges of the aluminum-plastic film; the pressing mechanism is used to press the aluminum-plastic film during cutting to ensure the accuracy and stability of cutting;

[0013] 6. Full bins and empty bins are used to hold materials to be processed. Chain conveyors are used to transport materials between their own bins. The transport mechanism is used to transport the plates from full bins to empty bins. The lifting mechanism is used to control the lifting of full bins or empty bins, so as to adjust the height of the bins during material transportation and ensure a smooth material transportation process.

[0014] 7. Compared with the traditional manual operation of placing the battery cell on the hot pressing workbench, there is no need for manual contact or proximity to the hot pressing workbench, which can improve the safety of battery cell production. Instead, the battery cell only needs to be placed on the conveyor belt and abutted to the first position. The operation is convenient and can ensure the accuracy of the battery cell placement position.

[0015] 8. The third mounting plate can be moved in the vertical and horizontal directions under the cooperation of the first driving member and the second driving member, and when the battery cell and the third mounting plate after being aligned in the first position are both at the intersection, the air pump is driven to put the air nozzle in a negative pressure state, and the battery cell can be adsorbed at this time to complete the picking up of the battery cell, and the posture of the battery cell after alignment can be maintained to ensure the consistency of the battery cell before hot pressing. After moving to the hot pressing workbench, the battery cell can be slowly placed on the hot pressing workbench through the cooperation of the air pump and the first driving member, realizing the automatic pick-up and place function of the battery cell;

[0016] 9. By setting the first probe, the hot pressing assembly can perform short circuit testing while hot pressing and shaping the battery cell, thereby improving the production efficiency of the battery cell;

[0017] 10. A plurality of areas for abutting and aligning the power cells are formed between the third baffle plate and the plurality of second alignment plates, so that when the battery cell is located between the two second alignment plates, the first alignment block can be driven to slide and abut the battery cell to the second alignment plate by starting the first driving mechanism to complete the preliminary alignment of one side of the battery cell, and then the second alignment block can be driven to slide and abut the battery cell to the baffle plate by starting the second driving mechanism to complete the alignment process of the battery cell, thereby realizing the precise positioning of the battery cell and facilitating the transfer of the battery cell by each transfer mechanism;

[0018] 11. By providing a plurality of first alignment blocks, the contact area of ​​the battery cells can be increased, further improving the alignment effect;

[0019] 12. By setting an infrared sensor, cooperating with a controller and a stepper motor, when the battery cell is in the detection area, the infrared sensor can send a signal to the controller, so that the controller sends a start signal to the stepper motor, so that the stepper motor automatically controls the second conveyor belt to drive the battery cell to be transported, which is convenient for the staff to perform intermittent loading operations;

[0020] 13. Compared with the traditional manual folding of the tabs, it is only necessary to place the tabs of the battery cell on the bending block, and the tabs can be driven by the abutment mechanism to cooperate with the bending channel for automatic bending, which can improve production efficiency. The tabs are bent under the limiting action of the first centering block, the alignment block, the bending block and the abutment mechanism in all directions, which can ensure the bending accuracy of the tabs, so that the bending position of the tabs is unified, and the quality and consistency of the products are improved;

[0021] 14. When the pole ear and the bending block move downward at the same time to perform the bending operation, the first spring is compressed and deformed to provide an upward thrust to the bending block, so that the bending block slides downward with the pole ear and provides an upward support to the pole ear, thereby further improving the upper and lower clamping effect of the abutment mechanism and the bending block, stabilizing the bending effect, and after the bending process is completed and the battery cell is taken out, the first spring can drive the bending block to complete the reset upward, which is convenient for the subsequent bending operation of the battery cell;

[0022] 15. By providing a second spring, after the bending process is completed and the battery cell is taken out, the second spring can drive the slider to drive the alignment block to slide away from the first centering block to complete the reset, so as to facilitate the subsequent bending operation of the battery cell;

[0023] 16. The flipping mechanism is used to flip the battery cell; the positioning mechanism positions the flipped battery cell to ensure that the battery cell is in the correct position for subsequent processing or treatment; the transportation mechanism is used to transport the flipped battery cell from the flipping mechanism to the positioning mechanism; the use of automation saves manpower and material resources and provides more accurate flipping positioning;

[0024] 17. When the battery cell to be packaged is located at the work station fixture and the battery cell pole ear is located on the support block, the upper top sealing block and the lower top sealing block are driven by the first driving component to slide close to each other until they respectively abut against the upper and lower sides of the aluminum-plastic film, so as to complete the top sealing process. During the pressing process, the second driving component drives the horizontal limit block to abut against the outer side of the pole ear in the direction of the second centering block, so that the two pole ears are centered in the direction of the second centering block, that is, the internal direction, so that the pole ear is positioned in the limit opening formed by the vertical limit block, the horizontal limit block, the second centering block and the support block, and the positioning of the pole ear is completed, so that the pole ear is not easily offset by force during the pressing and packaging process of the aluminum-plastic film on the upper and lower sides, thereby improving the sealing effect and consistency of the battery cell;

[0025] 18. When the horizontal limit block moves toward the second center block, the spring can buffer the horizontal limit block, reduce the impact of the horizontal limit block on the tab, and reduce the possibility of damage to the tab. After the pressing process is completed, the spring can provide a restoring force to drive the horizontal limit block to reset, which can improve the convenience of operation.

[0026] 19. The U-shaped circulating conveyor line is used to convey the station fixtures. Compared with the single-line assembly line, the structural design is more compact and reasonable and can reduce the occupied space. Compared with the folding equipment set up separately on the production line, the second station fixture can complete the folding process of the aluminum-plastic film during the circulating conveying process, and no additional equipment station is required, saving space;

[0027] 20. When loading the aluminum-plastic film shell, the fourth driving member is started to drive the second air pump to move until it abuts against and connects with the first air hole on the second station fixture. At this time, the second air pump is started to evacuate through the first air hole and the air channel, so that the second air hole continuously produces an adsorption effect on the aluminum-plastic film shell on the folding plate, so that the aluminum-plastic film shell can always fit with the folding plate during the folding process, and the aluminum-plastic film shell is prevented from being separated from the folding plate due to its own gravity, thereby enhancing the folding effect of the aluminum-plastic film shell;

[0028] 21. When the folding plate is attached to the fourth mounting plate, the tension spring can continuously provide restoring force to the connecting part, so that the connecting part can transmit force to the rotating rod, and the rotating rod transmits force to the folding plate. Therefore, during the transportation of the fixture at the second station, the folding plate can continuously provide stable pressure to the aluminum-plastic film shell to complete the positioning of the aluminum-plastic film shell, which is convenient for the subsequent top and side sealing process.
