Along with the rapid development of automobile energy and electric automobile industry, the application of lithium batteries in new energy automobiles is more and more widespread, a plurality of battery cells are generally adopted and assembled into a special battery cell module to serve as a power source of the whole automobile, and the mode is basically accepted and widely used in the industry. Therefore, the demands on battery assembly, arrangement and processing in the market at present are larger and larger, and the market potential is larger.
In daily life, because the energy provided by a single battery cell is far from enough, 2-3 battery cells are assembled into a battery pack under the requirement of obtaining a larger energy body, and materials such as a heat conducting plate, foam and the like are also contained in the battery pack, so that the battery cell has a good heat dissipation effect in the use process, but the energy stored by the single battery cell pack is very small, and in order to obtain a larger energy body, the battery packs are required to be stacked to form the battery cell module.
The traditional electric core stacking adopts a working mode of manual stacking, but the traditional stacking mode has lower efficiency and needs to consume a great deal of manpower.
In order to release manpower and improve the efficiency of cell stacking, the technical scheme of the application provides a cell stacking production line. The technical proposal is as follows:
the cell stacking line is described in further detail below with reference to fig. 1 to 10.
As shown in fig. 1, the three-dimensional structure schematic diagram of the cell stacking production line provided by the application is shown, the cell stacking production line comprises a conveying part 1, a feeding part 2 and a stacking part 3, the conveying part 1 comprises a jig 11, a conveying line and a conveying power device for driving the jig 11 to act along the conveying line, the feeding part 2 comprises a material storage part 22 and a material carrying device 21 for carrying materials from the material storage part 22 to the conveying part 1, and the stacking part 3 comprises an extraction mechanism 31 for extracting cell modules from the conveying part 1 and a stacking mechanism 32 for stacking the cell modules.
In the process of stacking materials into the battery cell module, the materials are required to be transported and conveyed, then the materials are stacked, then the battery cell packages formed by stacking are stacked again, and then the battery cell module required by us is formed, a feeding part 2, a conveying part 1 and a stacking part 3 are arranged on a battery cell stacking production line, the battery cell packages are stacked when transported and conveyed through the matching of the feeding part 2 and the conveying part 1, and the battery cell packages are stacked into the battery cell module through the stacking part 3, so that the battery cell stacking production line realizes automatic production of battery cell stacking, and the production efficiency is quickened while the labor cost is saved.
In one implementation, the cell stacking production line includes only one feeding portion 2, and the feeding portion 2 is located at one side of the conveying line.
When the cell stacking production line has only one feeding part 2, the material storage part 22 needs to contain all types of materials to be stacked, so that the materials can be stacked into a cell package at the feeding part 2, that is, the cell feeding part 2 needs to extract all materials to be stacked, and the materials are stacked into the cell package at a designated position according to the material sequence required by the process.
Of course, in another implementation, as shown in fig. 1 and fig. 2, the cell stacking production line includes at least two feeding portions 2, where the at least two feeding portions 2 are sequentially arranged on one side or two sides of the conveying line according to the types of materials held by the material storage portions 22 included in each feeding portion, the required sequence of stacking materials during stacking of the cells, and the conveying direction of the conveying line.
In actual production, the electric core package comprises electric core package upper end cover, electric core package lower end cover, electric core, heat insulating board, foam material and other materials, through the arrangement of a plurality of material loading parts 2, when the electric core package of pre-stacking is carried on the conveying line, the stacking of one material is completed through each material loading part 2, and when the conveying stage is finished, the stacking action of all materials can be completed, so that the electric core package is formed, and in addition, when the sequence of material stacking or the material type required during the stacking of the electric core package is changed, the arrangement mode of the material loading parts 2 can adapt to the change.
In the present embodiment, the material storage portion 22 includes a material containing table and a regularizing device 221 for regularizing materials, wherein: the material containing table comprises a material containing lifting device 232 and a material containing plate 231, and the material containing lifting device 232 drives the material containing plate 231 to lift; the regulating device 221 comprises a regulating power device and a regulating head, and the regulating power device drives the regulating head to do clamping action.
In actual production, because the material is in a stacked state, when the material is grabbed from the material storage part 22 in the later process, the stacked height can be changed each time, the change can cause the material taking of the later process to be required to be continuously adjusted to take the material height, and the material taking process becomes difficult.
Because the position of the material taken out from the material storage part is not fixed, the material cannot directly enter the first guide rail to be stacked, therefore, the material storage part 22 is further provided with a regulating device 221, and the fixed position can be ensured by the action of the regulating device 221, so that the condition of entering the first guide rail to be stacked is met, and meanwhile, the material taking error generated during the later material taking is avoided because of the position fixing.
In this embodiment, the regular power device is a cylinder, and of course, the regular power device may also be a power device such as a hydraulic cylinder or a servo screw, where the type of the regular power device is not limited; the regular head is made of polycarbonate, so that the material is prevented from being damaged under the condition of ensuring that the regular head can have a regular function, and of course, the regular head can also be made of other materials with certain elasticity, such as rubber and the like, and the material of the regular head is not limited.
Because of the presence of the alignment device 221, the material undergoes the handling steps from the material holding table to the alignment device 221 and from the alignment device 221 to the jig 11 during handling, thus requiring two handling devices, so in this embodiment, the material handling device 21 includes a first handling device 211 for handling the material in the material holding table to the alignment device 221 and a second handling device 212 for handling the aligned material to the jig 11, as shown in fig. 10.
Through the setting of first handling device 211 and second handling device 212, when first handling device 211 carries the material to regular device 221, second handling device 212 carries the material that is regular in the regular device 221 to tool 11 simultaneously, has still accelerated material handling efficiency when having guaranteed that the electricity core is stable.

In order to avoid collision and friction when materials are conveyed and stacked, the materials cannot be directly placed on a conveying line, and therefore a specific component is required for lifting, in this embodiment, a jig 11 is used for lifting the materials.
In order to realize the function of carrying the jig 11 on the conveying line, the conveying line is provided with a sliding rail 124, a sliding block 125 is arranged at the bottom of the jig 11 corresponding to the sliding rail 124, and the material is driven to be carried on the conveying line through the sliding of the jig 11, meanwhile, because the connecting mode of the sliding rail 124 and the sliding block 125 is adopted, the jig 11 only moves the displacement amount identical to the pushing amount on the premise of giving a certain pushing amount, and the conveying accuracy of the conveying line is further improved, and the belt conveying or the walking beam conveying can be used on the premise of ensuring the conveying accuracy, so that the repeated description is omitted.
However, in actual production, the belt conveying and the walking beam conveying can cause unstable conveying due to assembly errors or servo motor parameter setting problems, compared with the belt conveying and the walking beam conveying, the conveying mode of the sliding rail 124 and the sliding block 125, which is matched with each other, only depends on the sliding of the sliding block 125 on the sliding rail 124, the conveying mode is simple and efficient, the unstable conveying phenomenon generated in the conveying process can be avoided,
in actual production, under the condition of various materials, the number of the feeding parts 2 is increased, the length of the conveying line is prolonged, and the plane space occupied by the conveying line is reduced while the conveying and recycling functions are ensured through the design that the first guide rail is positioned above the second guide rail, so that the plane occupied space of the whole machine is reduced.
It can be understood that after the jig 11 completes material conveying and cell stacking on the first guide rail, the material needs to flow into the second guide rail and then wait to flow into the first guide rail again, so that the transfer device 12 is disposed at the end of the first guide rail, as shown in fig. 3, 4 and 5, the transfer device 12 is provided with a transfer lifting device 123, a transfer platform 121 and a lifting cylinder 122, the transfer lifting device 123 drives the transfer platform 121 to lift between the end of the first guide rail and the beginning of the second guide rail, the lifting cylinder 122 is used for lifting the jig 11 conveyed from the first guide rail, and the transfer platform 121 is further provided with a sliding rail 124 butted with the first guide rail and the second guide rail.
Therefore, when the stacking of the battery cell packages is completed, the jig 11 and the battery cell packages can slide from the first guide rail to the transfer platform 121 through the sliding rail 124 on the transfer platform 121, the lifting cylinder 122 on the transfer platform 121 lifts the jig 11, so that the battery cell packages can be conveniently taken out later, then the lifting cylinder 122 descends, the transfer platform 121 descends to the position where the transfer lifting device 123 is in butt joint with the second guide rail under the driving of the transfer lifting device 123, and then the empty jig on the transfer platform 121 is pushed to the second guide rail under the action of external force pushing, so that the function that the jig 11 is transferred from the first guide rail to the second guide rail is realized.
Similarly, a transfer device 12 may be disposed at the end of the second guide rail and the top end of the first guide rail, so that the empty fixture is transported from the second guide rail to the first guide rail, and no further description is given here.
When materials are stacked on the jig 11, because the battery pack process is limited, there is no adhesive between the materials, in order to ensure that the materials are kept at a stable position on the jig 11, in this embodiment, as shown in fig. 4 and 5, the jig 11 includes a bottom plate, a first set of guide posts 111 and a lifting plate 112, the periphery of the bottom plate is provided with the first set of guide posts 111 for guiding and guiding the materials, the lifting plate 112 for lifting the materials is slidably connected on the first set of guide posts 111, and a gap 126 for the lifting cylinder 122 to act is left in the middle of the bottom plate.

In actual operation, when the lifting cylinder 122 of the transfer device 12 performs lifting action, because the cooperation of the sliding rail 124 and the sliding block 125 cannot lift the whole jig 11, a gap 126 is left on the bottom plate for the lifting cylinder 122 to operate, so that the lifting cylinder 122 can perform lifting action on the lifting plate 112 through the gap 126, and meanwhile, in order to ensure the stability of the lifting plate 112 during lifting, the lifting plate 112 is slidably connected to the first set of guide posts 111.
After the materials are stacked on the jig 11, a battery pack is formed, and the battery pack needs to enter the stacking portion 3 to stack the battery modules, so a station for carrying the battery pack is required between the first guide rail and the stacking portion 3, and thus in this embodiment, an extraction mechanism 31 is provided, as shown in fig. 6, 8 and 9, the extraction mechanism 31 includes a mounting frame 313, an extraction power device 312, an extraction head 314 and a second set of guide posts 311 for guiding the materials to be extracted, where: the extraction power device 312 is arranged on the mounting frame 313, the extraction head 314 is arranged on the extraction power device 312, and the second group of guide posts 311 are arranged around the extraction head 314; the extraction power device 312 drives the extraction head 314 to move up and down, traverse, and/or clamp.

The stacking of the battery cell packs requires that the extraction mechanism 31 can have a larger stroke in the vertical direction, in order to avoid unstable battery pack conveying process caused by longer stroke, the extraction mechanism 31 only needs to discharge at the highest point of the stacking part 3 each time through the storage lifting device 322, and the storage lifting device 322 can drop the distance of one thickness of the battery cell pack after each time of discharging so as to discharge the next battery cell pack.
The second group of guide posts 311 and the third group of guide posts 321 are matched with the first group of guide posts 111 and the second group of guide posts 311 in use, so that the stability of materials in the battery cell package can be ensured in the discharging process of the battery cell package.
When the number of the battery cell packages reaches a preset value, the blanking rotating device 323 rotates ninety degrees to rotate the plurality of battery cell packages stacked in the vertical direction to the horizontal direction, so that the battery cell modules are conveniently formed by bolt fixing in the subsequent process.
In summary, according to the application, through the cooperation of the feeding part and the conveying part, the stacking of the battery cell packages is completed while the material conveying is realized, and the battery cell packages are stacked into the battery cell module through the stacking part, so that the battery cell stacking production line realizes the automatic production of battery cell stacking, saves the labor cost and accelerates the production efficiency.
