[0002] During the production process of solar cell sheets, the welding of a string welding machine and the non-destructive cutting of a dicing machine are involved. During the batch production process of the string welding machine and the dicing machine, the phenomenon of battery sheet throwing is likely to occur in the machine. The randomly stacked battery sheets after throwing are prone to breakage.

In addition, during the production process of battery sheets in an off-line scenario of the machine, it may also be necessary to stack the battery sheets. At this time, if manually stacked, the manual correction is slow, the correction is not standardized, and the stacking efficiency is low. Therefore, it is urgent to design a device that can realize automatic stacking of battery sheets for automatic stacking of machine-thrown battery sheets or automatic stacking of battery sheets in an off-line scenario.

The installation height of the through-beam sensor 5 at the corner of the collection box 1 determines the preset maximum stacking number of battery cells in the collection box 1. The through-beam sensor 5 is a through-beam light sensor, one for transmitting signals and the other for receiving signals. When the battery cells in the collection box 1 are stacked to a certain position, the battery cells will block the emitted light of one through-beam sensor 5, and the other through-beam sensor 5 cannot receive the signal, so the signal is transmitted to the control unit. The control unit controls the string welding machine to shut down or the alarm to sound, reminding personnel to circulate the battery cells in the collection box 1.

In other embodiments, two opposing beam sensors 5 can also be used as cell sensors. Each time a cell falls, the transmission signal is blocked for a short time. The opposing beam sensor 5 transmits the signal to the control unit. The control unit receives the signal of a cell falling. That is, the opposing beam sensor 5 is blocked for a long time, and the controller believes that the cells are stacked to the preset maximum stacking number. The opposing beam sensor 5 is blocked for a short time, and the controller believes that a cell has fallen in the collection box. In addition, when the collection box of the utility model is installed in the collection area of ​​the cell thrown by the stringing machine or the dicing machine, the cell sensor does not need to be set in the collection box.

The pressing blowing block 4 is obliquely installed on the fixing member 6, and the narrow slit 7 of the pressing blowing block 4 faces downward to the battery cell below. The pressing blowing block 4 blows air to the battery cell below through the narrow slit to press the battery cell to prevent the battery cell from drifting after being regularized.

[0029] The automatic cell stacking device also includes a cell pad 9, which is arranged at the bottom of the collection box 1. The fixed stopper 23 and the telescopic stopper 21 serve as the side reference planes of the cell in the collection box 1, and the pad 9 serves as the bottom reference plane of the bottommost cell in the collection box 1.

[0030] The automatic battery stacking device of the utility model can be directly installed in the battery collection area of ​​the stringing machine or the dicing machine, and the battery directly falls into the collection box 1, or it can be used for automatic correction of manually stacked battery in the machine offline scenario. The battery is first placed in the collection box 1 manually. After a battery falls into the collection box 1, the battery sensor senses the battery and sends a signal to the control unit. The control unit controls the separation blowing block 3 to separate the battery by blowing air to the battery, and prevents the subsequent regularization by debris and impurities. At the same time, the control unit controls the telescopic block 21 of the regularization mechanism 2 through the driving member 22 to extend and contact the battery. At this time, the control unit controls the separation blowing block 3 to stop blowing, and the telescopic block 21 pushes the battery to cooperate with the fixed The fixed block 23 arranges the battery cells. After the arrangement is completed, the control unit controls the telescopic block 21 to start retracting through the driving member 22.
