Description

Technical Field

[0001] The utility model relates to a device for regularly stacking battery sheets, belonging to the field of solar cell production equipment. Background Art

[0002] In the photovoltaic industry, cell surface treatment is a crucial step. Passivation machines coat and repair the cut surfaces, thereby improving the cell's power generation efficiency. This coating repair requires high flatness on the sides of stacked cells. Before entering the passivation machine, stacked cells are placed on a dedicated carrier. To ensure the coating repair requirements, the stacked cells must be aligned before entering the passivation machine.

[0003] The regular alignment method used in the past is to place the entire stack of battery cells into a material box and then use a mechanism to drive the pressing plate to fit the sides of the entire stack of battery cells one by one multiple times, and finally make the sides of the battery cells fit the inner wall of the material box, so as to achieve regular alignment of the sides of the entire stack of battery cells; the disadvantage of the above alignment method is that: there is an adsorption force between the smooth battery cells, which makes it difficult for the protruding edges of the battery cells to retract into the entire stack of battery cells. At this time, the rigid pressing plate is directly close to the side of the entire stack of battery cells, which easily crushes the battery cells with protruding edges, resulting in an increased product scrap rate. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the present invention provides a battery cell regular stacking device that can improve the stacking accuracy of battery cells and the efficiency of regular alignment of battery cells, thereby reducing the product scrap rate.

[0005] The battery cell stacking device described in this utility model includes a stacking box for holding the battery cells. The stacking box can be tilted so that the battery cells placed in the box slide in the tilted direction and align their long and short sides with the battery cells below. The stacking box is also equipped with an air knife on the side that blows air into the box to promote the alignment of the battery cells inside the box. The air knife can output air into the gaps between the battery cells, assisting the battery cells in sliding within the stacking box and providing the thrust required for battery cell alignment.

[0006] In addition, the side of the sorting box is equipped with a detection device to monitor whether the battery cells are neatly stacked, and a long-side straightening mechanism and a short-side straightening mechanism that use thrust to align the long and short sides of the stacked battery cells. If the battery cells are not aligned neatly due to the tilting of the sorting box and the assist of the air knife, the detection device will feedback a signal to the long-side straightening mechanism and / or the short-side straightening mechanism, which will use thrust to align the long and short sides of the stacked battery cells.

[0007] Among them, the long side regularization mechanism includes a long side alignment motor, a long side push claw and a crank slider linkage mechanism therebetween. The long side alignment motor can drive the long side push claw to move forward and backward through the crank slider linkage mechanism, thereby pushing the battery cell forward to align the long sides of the battery cell.

[0008] Among them, the short-side regularization mechanism includes a short-side pushing claw, a short-side alignment motor and a rocker arm therebetween. One end of the rocker arm is fixedly connected to the motor shaft of the short-side alignment motor, and the other end is connected to the short-side pushing claw. The short-side alignment motor can drive the rocker arm to swing within a certain angle range, thereby realizing the action of pushing the battery cell forward with the front face of the pushing claw to align the short sides of the battery cell.

[0009] Preferably, the relative height between the air knife and the sorting box is adjustable so that the air discharged by the air knife always acts on the top battery cell area that has just been stacked.

[0010] Preferably, the relative heights of the long edge aligning mechanism, the short edge aligning mechanism and the aligning box are adjustable so that the alignment force applying parts of the long edge aligning mechanism and the short edge aligning mechanism can act on the battery cells that are not aligned with other battery cells.

[0011] Specifically, the reorganized material box includes a material box bottom plate and two vertical side plates, the two side plates are located on two sides of the same corner of the material box bottom plate, and the two side plates and the material box bottom plate are perpendicular to each other.

[0012] Among them, a material box tilting cylinder is provided under the material box bottom plate, and the material box bottom plate is hinged to the piston rod of the material box tilting cylinder. Under the lifting action of the material box tilting cylinder, the material box can be tilted toward the corner where the side plate is located.

[0013] Furthermore, the tidying box is entirely arranged on a mounting seat, and a lifting electric cylinder is provided below the mounting seat, and the tidying box can be lifted and lowered as a whole under the action of the lifting electric cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Improve the stacking accuracy and alignment efficiency of battery cells:

[0016] This utility model uses a tiltable aligning box to allow the cells to slide naturally under the tilting action, aligning the long and short sides of the cells below. Air blades are then used to output airflow into the gaps between the cells, assisting the cells in sliding within the aligning box and providing the thrust required for alignment. This accelerates the alignment process and improves the efficiency of alignment. Furthermore, long-side and short-side aligning mechanisms are provided. When the detection device detects cell misalignment, these mechanisms can be used to quickly adjust the cells, improving the stacking accuracy of the cells.

[0017] 2. Reduce product scrap rate:

[0018] In traditional alignment methods, the adsorption forces between smooth cells make it difficult for protruding cell edges to retract, making them easily crushed by rigid pressure plates. However, this new method reduces physical damage to the cells through natural sliding and air knife-assisted propulsion, thereby lowering product scrap rates. Furthermore, the design of the long and short edge alignment mechanisms also takes flexible alignment into account, avoiding rigid collisions and further protecting the cells.

[0019] 3. Strong adaptability:

[0020] During the stacking process of the battery cells, the relative height of the air knife and the sorting box can be changed, ensuring that the air outlet of the air knife always acts on the top battery cell area that has just been stacked; the relative height of the long-side regularization mechanism and the short-side regularization mechanism and the sorting box can also be changed, so that these mechanisms can accurately act on misaligned battery cells, enhancing the adaptability and flexibility of the device.

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] However, the description of the present invention is merely an embodiment of structural and even functional description, and the scope of rights of the present invention is not limited by the embodiments described herein.

[0027] For example, multiple embodiments may have various modifications and various forms, and it should be understood that the scope of rights of the present invention includes equivalents that can implement the technical idea.

[0028] The battery cell stacking device of this embodiment includes a storage box for storing battery cells 14. The storage box includes a storage box bottom plate 9 and two vertical side plates 4. The two side plates 4 are located on either side of the same corner of the storage box bottom plate 9, and the two side plates 4 and the storage box bottom plate 9 are perpendicular to each other. A storage box tilting cylinder 10 is provided below the storage box bottom plate 9. The storage box bottom plate 9 is hingedly connected to the piston rod of the storage box tilting cylinder 10. Under the lifting action of the storage box tilting cylinder, the storage box can be tilted toward the corner where the side plates 4 are located, so that the battery cells 14 placed in the box can slide in the tilted direction and align the long and short sides of the battery cells 14 below.

[0029] In addition, the side of the sorting box is also provided with an air knife 7 that can blow air into the sorting box to promote the alignment of the battery cells 14 in the box. It is also provided with a detection device for monitoring whether the battery cells 14 are stacked neatly (i.e., a long side detection optical fiber sensor 3 and a short side detection optical fiber sensor 5), and a long side regularization mechanism and a short side regularization mechanism that can align the long and short sides of the stacked battery cells 14 through thrust. The sorting box is set as a whole on a mounting base 16, and a lifting electric cylinder 11 is provided below the mounting base 16. Under the action of the lifting electric cylinder 11, the sorting box can be lifted and lowered as a whole, thereby achieving a variable relative height between the air knife 7 and the sorting box, so that the air outlet of the air knife 7 always acts on the top battery cell area that has just been stacked. By lifting the whole box, the relative height between the long side regularization mechanism, the short side regularization mechanism and the sorting box can also be changed, so that the alignment force application parts of the long side regularization mechanism and the short side regularization mechanism can act on battery cells that are not aligned with other battery cells 14.

[0030] The long side regularization mechanism of this embodiment includes a long side alignment motor 1, a long side push claw 2 and a crank slider linkage mechanism 12 therebetween. The long side alignment motor 1 can drive the long side push claw 2 to move forward and backward through the crank slider linkage mechanism 12, thereby pushing the battery cell 14 forward to align the long sides of the battery cell 14.

[0031] The short edge regularization mechanism of this embodiment includes a short edge pushing claw 6, a short edge alignment motor 8 and a rocker arm 13 therebetween. One end of the rocker arm 13 is fixedly connected to the motor shaft of the short edge alignment motor 8, and the other end is connected to the short edge pushing claw 6. The short edge alignment motor 8 can drive the rocker arm 13 to swing within a certain angle range, thereby realizing the action of the short edge pushing claw 6 pushing the battery cell 14 forward from the front to align the short edges of the battery cell 14.

[0032] Single cells are transported to the pallet 15 in the sorting box for stacking. During this process, the sorting box tilts, causing the cell 14 to slide naturally under the tilting effect, aligning the long and short sides of the cell below. Air blades 7 output air into the gaps between the cells, assisting the cell in sliding within the sorting box and providing the thrust required for cell alignment. This accelerates the cell alignment process and improves the efficiency of sorting. At the same time, when the detection device finds that the cell is misaligned, it can quickly adjust it through the long and short side sorting mechanisms to improve the stacking accuracy of the cell.

[0033] Of course, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of the embodiments of the present invention. The present invention is not limited to the above examples. Equivalent changes and improvements made by ordinary technicians in this technical field within the essential scope of the present invention should all fall within the scope of the patent of the present invention.
