Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of battery cell packaging equipment, and in particular to an integrated machine for sealing and punching the top side of a battery cell. Background Technology
[0002] In traditional battery packaging production, specialized punching equipment punches grooves into the battery casings made of aluminum-plastic film or other materials. The punched casings are typically stacked and framed. Workers or transport equipment then move the entire frame of casings to the packaging equipment. A robotic arm on the packaging equipment loads the casings into a lamination mechanism, where the packaging equipment places the battery cells into the grooves in the casings. The lamination mechanism then folds the casings together and performs top sealing, side sealing, and edge trimming to form the battery. In this production method, the long-distance transport of large quantities of battery casings between the punching and packaging equipment makes them susceptible to scratches, collisions, and drops, resulting in surface damage and affecting product quality.

[0029] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, a battery cell top-side sealing and punching integrated machine includes a packaging mechanism 100, a punching mechanism 200, a battery cell loading mechanism 400, and a battery unloading mechanism 500. The packaging mechanism 100 includes a first frame 110, a film-forming assembly 120, a top sealing device 130, a side sealing device 140, and a first edge-cutting device 150. The top sealing device 130, the side sealing device 140, and the first edge-cutting device 150 are sequentially arranged along a straight line on the first frame 110. The first frame 110 is provided with a first material transfer assembly 160. The punching mechanism 200 is disposed on one side of the first frame 110 and is used to punch holes in the battery casing. A second material transfer assembly 300 is disposed between the punching mechanism 200 and the first frame 110. The battery cell loading mechanism... The first frame 110 has a battery unloading mechanism 400 disposed on one side of the first frame 110. The second transfer assembly 300 can transfer the battery casing with the punched hole completed from the punching mechanism 200 to the film-forming assembly 120. The cell loading mechanism 400 is used to load the cell onto the battery casing at the film-forming assembly 120. The film-forming assembly 120 is used to fold the battery casing in half to form a film for packaging the cell. The first transfer assembly 160 is used to complete the material transfer between the film-forming assembly 120 and the first edge-cutting device 150 so that the top sealing device 130 completes the top sealing of the battery, the side sealing device 140 completes the side sealing of the battery, and the first edge-cutting device 150 completes the edge-cutting of the battery. The battery unloading mechanism 500 is used to unload the battery to the packaging mechanism 100.
[0030] During the production process, the punching mechanism 200 punches indentations into the battery casing, and then the second material transfer component 300 conveys the punched battery casing to the film-coating component 120. The cell feeding mechanism 400 then conveys the cells into the indentations on the battery casing of the film-coating component 120, and the film-coating component 120 folds the battery casing in half to form a film, thereby covering the cell with the battery casing to form a semi-finished battery. Subsequently, the top sealing device 130 performs top sealing, the side sealing device 140 performs side sealing, and the first edge-cutting device 150 performs edge-cutting of the battery casing. The material transfer between the film-coating component 120 and the first edge-cutting device 150 is completed by the first material transfer component 160. Finally, the battery unloading mechanism 500 unloads the encapsulated battery. In the continuous production process of the integrated cell top and side sealing punching machine, each process can be carried out simultaneously, and adjacent processes can be seamlessly connected, improving production efficiency.
[0031] The integrated cell top-side sealing and punching machine provided by this utility model integrates the punching mechanism 200, the cell feeding mechanism 400, the battery unloading mechanism 500, and the packaging mechanism 100 into one, thereby achieving seamless connection between processes such as battery casing punching and feeding, cell feeding, battery packaging, and battery packaging. It eliminates waiting time between processes, such as waiting for handling after punching and waiting for packaging after sealing, and avoids the process of long-distance handling and transfer of battery casings. It fundamentally avoids appearance damage caused by scratches, collisions, and drops, ensures product quality, and improves product yield.
[0032] In addition, the integrated battery cell top-side sealing and punching machine provided by this utility model compresses the space that originally required multiple independent devices and material buffer areas into the footprint of one device. It eliminates the need to reserve a large amount of space for material flow and operation channels between devices, resulting in a more compact layout and reduced factory floor space.
[0033] Reference Figure 1 According to some embodiments of the present invention, the cell feeding mechanism 400 is located on the left side of the first frame 110, the battery unloading mechanism 500 is located on the right side of the first frame 110, and the cratering mechanism 200 is located on the front or rear side of the cell feeding mechanism 400. The layout is reasonable and facilitates the assembly and subsequent maintenance of each mechanism.
[0034] In batteries using materials such as aluminum-plastic film as the battery casing, the edge parallel to the crease on the folded battery casing is usually called the top edge, and the edge perpendicular to the crease is called the side edge. The battery cell's tabs generally pass between the two top edges of the folded battery casing. In existing technology, after the side sealing is completed, only the side edges of the battery casing are usually trimmed, and the top edge of the battery casing is not trimmed or adjusted to avoid damaging the battery cell's tabs during trimming. However, this method, because the top edge of the battery casing is not trimmed, is prone to quality problems such as uneven top edges and excessive length.
[0035] Reference Figure 1 and Figure 4 According to some embodiments of the present invention, the punching mechanism 200 includes a second frame 210, a roll unwinding device 220 for supplying rolls of material, a roll cutting device 230 for cutting the rolls of material into battery casings, a punching mold 240 for punching out recesses in the battery casings, a second edge cutting device 250, and a third material transfer assembly 270. The roll unwinding device 220, the roll cutting device 230, the punching mold 240, the second edge cutting device 250, and the third material transfer assembly 270 are all disposed on the second frame 210. The third material transfer assembly 270 is used to sequentially transport the battery casings from the roll cutting device 230 to the punching mold 240 and the second edge cutting device 250. The second edge cutting device 250 is used to cut the top edge of the battery casings, and the first edge cutting device 150 is used to cut the side edges of the battery casings. The second material transfer assembly 300 is used to transport the battery casings at the second edge cutting device 250 to the film-forming assembly 120. With the above-mentioned configuration, the battery cell top and side sealing punching integrated machine provided by this utility model has a second edge cutting device 250 in the punching mechanism 200 to cut the top edge of the battery shell before battery packaging, thus pre-trimming the top edge of the battery shell. After the side sealing is completed, the second edge cutting device 250 can also be used to trim the side edge of the battery shell. In this way, the top and side edges of the battery shell can be trimmed, thereby improving product quality.
[0036] Reference Figures 1 to 3According to some embodiments of the present invention, the second material transfer assembly 300 includes a first moving device 310 and a second moving device 330. A first suction device 320 is installed on the first moving device 310. The second moving device 330 is disposed between the first frame 110 and the punching mechanism 200. The first frame 110 is provided with a battery cell feeding station 111 for feeding by the battery cell feeding mechanism 400. The second moving device 330 passes through the battery cell feeding station 111. The first moving device 310 is located on the side of the second moving device 330 closer to the punching mechanism 200. The end of the second moving device 330 away from the punching mechanism 200 is disposed opposite to the top sealing device 130. The film-forming assembly 120 includes a film-forming fixture 121 installed on the second moving device 330. The second moving device 330 is used to drive the film-forming fixture 121 to move between the first moving device 310 and the top sealing device 130. The second moving device 330 drives the film-forming fixture 121 of the film-forming assembly 120 to move between the first moving device 310 and the top sealing device 130, so that the feeding position of the first holding device 320, the feeding position of the cell feeding mechanism 400 and the working position of the top sealing device 130 are staggered, avoiding collisions and interference between the first holding device 320, the cell feeding mechanism 400 and the top sealing device 130, thereby smoothly realizing the feeding of battery casings by the first holding device 320 to the film-forming fixture 121, the feeding of cells by the cell feeding mechanism 400 to the film-forming fixture 121, and the top sealing device 130 to top seal the film-forming battery casings on the film-forming fixture 121.
[0037] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, two sets of film-forming assemblies 120 are arranged side by side, and two sets of top-sealing devices 130 are arranged. Since the film-forming assembly 120 usually takes longer to fold and form the film on the battery casing than other processes such as top sealing and punching, by setting two sets of film-forming assemblies 120 and two sets of top-sealing devices 130, the overall production efficiency at the film-forming assembly 120 can be improved, making the production rhythm of the film-forming assembly 120, the cell feeding mechanism 400, and the punching mechanism 200 more compatible, and achieving seamless connection between the film-forming assembly 120, the cell feeding mechanism 400, and the punching mechanism 200.
[0038] Reference Figure 2 and Figure 3According to some embodiments of this utility model, the film-forming assembly 120 includes a vertical bending device 122 and a horizontal bending film-forming device 123. The horizontal bending film-forming device 123 is disposed on the second moving device 330 and located on one side of the film-forming fixture 121. The vertical bending device 122 is disposed at the cell loading station 111. The horizontal bending film-forming device 123, the vertical bending device 122, and the film-forming fixture 121 can cooperate with each other to fold and form a film on the battery casing. During the film-forming process of the film-forming assembly 120, the film-forming fixture 121 fixes the first end of the battery casing, the cell loading mechanism 400 places the cell into the recess on the first end of the battery casing, and then the vertical bending device 122 pushes and bends the second end of the battery casing upwards. Then, the horizontal bending film-forming device 123 pushes and bends the second end of the battery casing horizontally, thereby folding and attaching the second end of the battery casing to the first end of the battery casing, thus realizing the folding and film-forming of the battery casing.
[0039] Reference Figure 4 and Figure 5 To facilitate the folding and film bonding of the battery casing, the punching die 240 is used to punch a dent at the first end of the battery casing, while the second end of the battery casing remains flat. Thus, the horizontal bending and film bonding device 123 can more easily push and bend the second end of the battery casing onto the first end of the battery casing. At the same time, the punching mechanism 200 is also equipped with a pre-pressing device 260, which is used to punch and form an indentation at the crease position of the battery casing, so that the battery casing can be folded more easily and the folding position is at the indentation, thereby improving the accuracy and efficiency of folding.
[0040] Reference Figure 5 In specific implementation, the second edge-cutting device 250 includes an edge-cutting fixture 251 and a lifting driver 252. The lifting driver 252 is mounted on a mounting plate 253, which is positioned opposite to the edge-cutting fixture 251. Two movable cutting blades 255 are mounted on the mounting plate 253, and fixed cutting blades 254 are respectively provided at opposite ends of the edge-cutting fixture 251. The two movable cutting blades 255 and the two fixed cutting blades 254 cooperate one-to-one to cut the two top edges of the battery casing before folding. The pre-pressing device 260 includes a pre-pressing plate, which is disposed on the mounting plate 253 and is positioned opposite to the edge-cutting fixture 251. Thus, the lifting driver 252 simultaneously drives the movable cutting blades 255 and the pre-pressing plate, thereby eliminating the need for an additional lifting driver 252 for the pre-pressing plate and achieving structural simplification.
[0041] It should be noted that in some other embodiments, the above-mentioned film-forming assembly 120 may also adopt other configurations. For example, the film-forming assembly 120 includes two film-forming jigs 121 and a rotary driver. The rotary driver is mounted on the second moving device 330, wherein the first film-forming jig 121 is mounted on the second moving device 330, and the second film-forming jig 121 is mounted on the rotary driver. The rotary driver can drive the second film-forming jig 121 to rotate and fold or unfold relative to the first film-forming jig 121. Thus, during the film-forming process, the two film-forming jigs 121 first adsorb the battery casing, and then the rotary driver drives the second film-forming jig 121 to rotate, thereby folding the battery casing in half to form a film.
[0042] Reference Figure 6 According to some embodiments of the present invention, the battery cell feeding mechanism 400 includes a third frame 410, a battery cell input device 420, a battery cell shaping device 430, a battery cell positioning device 440, a feeding robot 450, a fourth transfer component 460, and a fifth transfer component 470. The battery cell input device 420, the battery cell shaping device 430, the battery cell positioning device 440, the feeding robot 450, the fourth transfer component 460, and the fifth transfer component 470 are all disposed on the third frame 410. A battery cell temporary storage plate 480 is disposed between the battery cell input device 420 and the battery cell shaping device 430 on the third frame 410. The feeding robot 450, the fourth transfer component 460, and the fifth transfer component 470 cooperate to sequentially transport the battery cells from the battery cell input device 420 to the battery cell temporary storage plate 480, the battery cell shaping device 430, the battery cell positioning device 440, and the film-forming assembly 120. With the above settings, the cell feeding mechanism 400 can shape and position the cell before conveying it to the film bonding assembly 120. The shaped cell shape can better match the recesses on the battery casing, which not only makes it easier for the cell to be installed into the recesses on the battery casing, but also ensures the quality of the finished battery.
[0043] Reference Figure 2 According to some embodiments of the present invention, a battery testing device 170 is provided on the first frame 110. The battery testing device 170 is located between the side sealing device 140 and the first edge cutting device 150. Thus, the battery testing device 170 can be used to test the quality of the side-sealed battery, and the test results can be stored in the factory's production database.
[0044] In the specific implementation process, the first frame 110 is also equipped with a coding device. The coding device is used to code the batteries that have completed the inspection to form identification codes such as QR codes or barcodes on the battery casing. Thus, the battery production information stored in the factory's production database corresponds one-to-one with each identification code, so as to facilitate production traceability.
[0045] It should be noted that the first trimming device 150 described above can refer to the arrangement of the second trimming device 250, and will not be described in detail here.

The packaging component 520, the discharge conveying device 530, and the sixth transfer component 540 are all disposed on the fourth frame 510. A material frame 600 is placed on the discharge conveying device 530. The packaging component 520 is used to package the battery inside a separator. The sixth transfer component 540 is used to transfer and stack the battery from the packaging component 520 onto the material frame 600. The seventh transfer component 550 is used to transport the battery from the first trimming device 150 to the packaging component 520. With the above configuration, the battery unloading mechanism 500 can package the battery and complete the framing process. Packaging the battery inside the separator protects the battery during subsequent frame transport, buffering impacts and preventing damage.
[0047] It should be noted that all components of the battery feeding mechanism 500 can be referenced from existing packaging equipment, and the specific structure will not be described in detail here.
