Under the influence of static electricity, the waste is not easy to separate from the punched diaphragm, affecting the subsequent processing of the diaphragm. Based on this, the present application proposes a punching device for diaphragm production. Utility Model Content

[0026] The punching device for membrane production proposed in the present application also includes a collecting box 9, which is arranged below the waste adsorption structure and is used to collect waste generated by punching. The collecting box 9 is located below the first air blowing plate 13.

[0027] 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.

[0028] To sum up: when the punching device for diaphragm production is used, after the diaphragm strip to be cut moves to the punching area, the hydraulic telescopic rod 12 drives the connecting plate 5 and the punching head 12 to move downward until the pressing plate 3 is tightly fitted with the diaphragm strip, and the diaphragm strip is pressed by the pressing plate 3. The hydraulic telescopic rod 12 continues to extend so that the punching head 12 punches the diaphragm strip, and during the process of the hydraulic telescopic rod 12 continuing to extend, the hydraulic telescopic rod 21 extends, and the hydraulic telescopic rod 21 drives the vacuum suction cup 18 to move downward, so that the punching head 12 can punch the diaphragm strip. After the punching is completed, the vacuum pump 16 works, and the work of the vacuum pump 16 makes the waste material in contact with it The vacuum suction cup 18 is connected to the negative pressure, and the hydraulic telescopic rod 21 continues to extend until the vacuum suction cup 18 moves to the bottom of the base 1, and the rotating motor 20 works. The operation of the rotating motor 20 causes the vacuum suction cup 18 to rotate until the vacuum suction cup 18 is located between the first air jet plate 13 and the collection box 9, and the vacuum pump 16 stops working. The ion blower 14 works, and the operation of the ion blower 14 causes the first air jet plate 13 to spray air containing a large amount of evaporated ions. The gas sprayed by the first air jet plate 13 can be blown onto the waste material, eliminating the static electricity between the waste material and the vacuum suction cup 18, and can blow off the waste material, so as to separate the waste material from the vacuum suction cup 18. After the waste material and the vacuum suction cup 18 in contact with it are connected to the negative pressure, the hydraulic telescopic rod 12 shrinks, and the hydraulic telescopic rod 12 drives the punching head 12 and the pressing plate 3 to reset. In this process, the gas sprayed by the second air jet plate 11 can eliminate the static electricity on the film strip and the punching head 12, so as to facilitate the reuse of the punching head 12.
