The detection device is provided on the machine 1 and is arranged adjacent to the transport channel 11, the detection device is electrically connected to the rotating mechanism 4, and is used to detect the position of the pole lug of the strip sheet in the transport channel 11. The first direction 10 and the second direction 50 are arranged at an angle.

[0047] Specifically, the machine 1 is arranged at the outlet of the unwinding mechanism of the battery production line. The machine 1 is provided with a roller assembly, and the roller assembly forms a transport channel 11. The transport channel 11 is connected to the unwinding mechanism to receive the strip sheet provided by the unwinding mechanism. It can be understood that one side of the strip sheet is provided with one or more pole ears, and the multiple pole ears are evenly spaced. The cutter 516 cuts between the adjacent pole ears of the sheet, and the sheet can be cut into multiple pole pieces. Therefore, if the cutting position of the cutter 516 is incorrect, it will affect the shape of multiple pole pieces. Therefore, before the pole sheet is in the transport channel 11 and enters the cutting device 3, the detection mechanism can capture the image of the pole piece, and the image identifies the position of the pole ear, and then the deflection of the strip material can be obtained, which is fed back to the rotating mechanism 4 so that the rotating mechanism 4 controls the cutting mechanism 5 to rotate the corresponding angle, and then controls the cutting mechanism 5 to cut.

[0048] Further, the first direction 10 of the transport channel 11 is a horizontal direction, and the second direction 50 of the cutter mechanism 5 is a vertical direction, that is, the first direction 10 is perpendicular to the second direction 50. The rotation mechanism 4 controls the rotation angle of the cutter mechanism 5 to be plus or minus 5 degrees.

[0049] Through this embodiment, a rotatable and adjustable tool is used, so that the slicing equipment can control the accuracy of the electrode sheet after slicing.

The cutter device 3 includes a rotating mechanism 4 and a cutting mechanism 5, and the rotating mechanism 4 can drive the cutting mechanism 5 to rotate. When entering the cutting device 3, the detection device detects the position of the electrode ears of the strip sheet, and then calculates the lower cutting position of the cutting device 3, so the rotating mechanism 4 is controlled to adjust the position of the cutting mechanism 5, and then the cutting mechanism 5 cuts the strip sheet to produce positive / negative electrode sheets, so that the cut electrode sheets have high shape accuracy and accurate electrode ear positions.

[0052] Through this embodiment, the personnel first correct the position of the moving component so that the blade of the cutter 516 is perpendicular to the edge of the strip sheet, and this position is used as the initial position. Then the detection device detects the position of the pole ear, and the position of the pole ear can be used to know where the cutter 516 should cut, and the shape of the pole ear (i.e., the position of multiple edges) can also be used to determine whether the strip sheet is tilted, so as to determine in which direction and how many degrees the cutter 516 should rotate, and then control the motor component to make its rotating platform 42 drive the cutter mechanism 5 to rotate, so that the cutter 516 is perpendicular to the edge of the strip sheet, and then the shape of the pole piece cut out after cutting is accurate, that is, the shape is rectangular, and the pole piece will not be cut into a parallelogram.

The cutter assembly 51 is provided with a cutter 516, and a cutter gap 5161 is formed between the cutter 516 and the bearing surface 5131, through which the pole piece can pass. The pressing assembly 52 is connected to the cutter assembly 51, and can control the cutter 516 of the cutter assembly 51 to move up and down.

[0055] Through this embodiment, the unwinding mechanism feeds the sheet into the cutting device 3 along the first direction 10. During the feeding process, the detection device detects the position of the pole ear of the sheet to identify the position where the cutter assembly 51 needs to cut. After the sheet is in place, the transportation of the sheet in the transport channel 11 is suspended. The rotating mechanism 4 rotates the cutting mechanism 5 according to the image taken by the detection device, so that the cutter 516 rotates around the second direction 50, and then the cutter 516 moves vertically downward under the control of the pressing assembly 52 to cut the sheet into sheet-shaped pole pieces.

A sliding groove 515 is provided on the upper side of the sliding block 514, and the pressing assembly 52 is provided with a sliding boss 523, and the sliding boss 523 is abutted against the sliding groove 515, so that the sliding boss 523 can move in the sliding groove 515 along the first direction 10 and / or other horizontal directions, and can also rotate around the second direction 50 and / or the vertical direction, but cannot move along the second direction 50 and / or the vertical direction. The elastic member 517 is a spring, which is sleeved on the guide column 512, with one end abutting the base 511 and the other end abutting the sliding block 514, so that the base 511 and the sliding block 514 tend to move away from each other, preventing the cutter 516 from accidentally falling and cutting the sheet under the drive of gravity.

[0058] Furthermore, the tip of the cutter 516 coincides with the edge of the carrying surface 5131, and the sheet is cut by the scissor difference when the cutter 516 falls.

A tension spring 524 is also provided between the pressure block 522 and the bracket 521, and the tension spring 524 pulls the pressure block 522 so that the pressure block 522 has a tendency to move vertically upward, that is, to drive the cutter 516 away from the bearing surface 5131, so as to prevent the cutter 516 from accidentally falling and cutting the sheet under the drive of gravity. The driver includes a motor and a cam assembly 525, and the motor controls the cam assembly 525 to drive the cutter 516 to reciprocate, and the stroke of the cutter 516 can be controlled by the cam shape design.
