After the CCD camera collects the image of the first pole piece, data such as the size and the position of the first pole piece can be obtained, whether the size of the first pole piece is qualified is judged first, and if the size of the first pole piece is qualified, the second manipulator accurately adjusts the position of the first pole piece on the cutting station according to the position data.

Further, as shown in fig. 1, the solid-state battery dicing and stacking integrated machine further includes a dust removing device 800. Wherein, chamfer cutting device 420, dust collector 800 and defect detecting device set gradually along the delivery path of first pole piece material roll. The dust extraction device 800 is configured to clean a surface of the first pole piece.

It can be appreciated that the dust removing device 800 can remove dust particles on the surface of the first pole piece in an air purging manner, and can also remove dust particles on the surface of the first pole piece in a brush cleaning manner, so as to avoid the waste of the first pole piece from rising due to the influence of the dust particles on the accuracy of subsequent defect detection. After the chamfering and cutting operation is completed, the first pole piece is transferred from the cutting station to the belt conveyor, and the dust removing device 800 can clean the first pole piece on the belt conveyor. After the cleaning process is completed, the first pole piece is transferred to a first inspection station for defect inspection thereof.

It will be appreciated that the transfer of the first pole piece between the various stations may be accomplished by a handling robot.

In some embodiments, the glue applicator 200 and the curing apparatus 300 are each provided with one, and the glue application process and frame curing is performed on only one of the surfaces, such as the upper surface, of the first pole piece roll. In this embodiment, one of the surfaces of the first pole piece roll is coated with a solid electrolyte layer.

In other embodiments, two glue devices 200 are provided, and the two glue devices 200 are a first glue device and a second glue device, respectively. The curing devices 300 are provided in two, and the two curing devices 300 are a first curing device and a second curing device, respectively. Moreover, the first gluing device, the first curing device, the second gluing device and the second curing device are sequentially arranged along the conveying path of the first pole piece material roll.

The first gluing device is configured to glue one of the surfaces of the first pole piece roll, and the first curing device is configured to cure the glue frame on the surface. The second gluing device is configured to glue the opposite surface of the first pole piece roll, and the second curing device is configured to cure the glue frame on the surface. In this embodiment, both surfaces of the first roll of pole pieces are coated with a solid electrolyte layer.

It will be appreciated that since both the upper and lower surfaces of the first pole piece roll are provided with solid electrolyte layers, a frame can be manufactured on both the upper and lower surfaces of the first pole piece roll by means of two glue application devices 200 and two curing devices 300. When lamination is carried out, the second pole pieces can be placed on the upper side and the lower side of the first pole piece, and the solid electrolyte layers on the upper side and the lower side of the first pole piece are respectively contacted with the two second pole pieces correspondingly. Then, the first pole piece and the second pole piece may be alternately stacked.

In addition, if the uppermost and lowermost electrode plates of the solid-state battery cell are both first electrode plates, the corresponding glue spreading device 200 may be started, and glue is spread on the upper surface of the first electrode plate located at the lowermost side to manufacture a glue frame, and glue is spread on the lower surface of the first electrode plate located at the uppermost side to manufacture a glue frame, so that the glue frames do not need to be manufactured on the upper and lower surfaces of the two first electrode plates.
