[0034] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0035] In summary, when the diaphragm blanking and forming equipment is used, the diaphragm strip moves between the lower blowing plate 2 and the upper blowing plate 3 under the action of the transmission roller and other tools in the prior art, and the bottom of the diaphragm strip contacts the top of the workbench 1. During the movement of the diaphragm strip, the air with ions blown out by the lower blowing plate 2 and the upper blowing plate 3 neutralizes the static electricity on the surface of the diaphragm strip, which facilitates the blanking of the diaphragm strip. When the diaphragm strip needs to be blanked, the diaphragm strip stops moving. The hydraulic telescopic rod 1 6 drives the pressing frame 7 to move downward until the bottom of the pressing frame 7 contacts the top of the diaphragm strip. At this time, the pressing frame 7 and the pressing plate 13 press the diaphragm strip, and the hydraulic telescopic rod 2 12 extends. The hydraulic telescopic rod 2 12 drives the punching knife 8 fixedly connected thereto to move downward, and the punching knife 8 can cut the diaphragm strip. The cut diaphragm contacts the bottom of the pressing plate 13, and during the cutting process, the punching knife 8 can press the lifting plate 16 downward, so that the diaphragm and the waste can be completely separated. The diaphragm is separated from the waste material to facilitate separation. After cutting is completed, the hydraulic telescopic rod 6 contracts, and the hydraulic telescopic rod 6 drives the pressure frame 7 to move upward. During the contraction of the hydraulic telescopic rod 6, the vacuum pump 22 works, so that the vacuum suction cup 19 is connected to the diaphragm under negative pressure to prevent the diaphragm from adhering to the pressing plate 13. When the pressing frame 7 moves to the top of the rotation path of the rotating groove 9, the rotating motor 21 drives the rotating groove 9 to rotate. When the diaphragm is located above the conveyor belt 10, the vacuum pump 22 stops working and the blower 23 works. The work of the blower 23 causes the blowing holes on the blowing plate 18 to blow out air, and the blown air can blow the diaphragm so that the diaphragm can be separated from the support plate 17. The diaphragm falls on the conveyor belt 10 under the action of gravity, and the conveyor belt 10 can transport the diaphragm. The rotating motor 21 drives the rotating groove 9 to continue to rotate until the rotating groove 9 is reset, and the diaphragm strip moves, so that when another cutting section of the diaphragm strip moves to the top of the rotating groove 9, the equipment can continue to punch the diaphragm strip.
