[0024] The upper module 100 includes an upper die base 110, an upper cushion block 120, a punching fixed seat 130, a punching rod 140, a punching recess 150, a stripping plate 160 and a stripping rod 170, wherein the upper cushion block 120 is located at the bottom end of the upper die base 110 and the punching fixed seat 130 is located at a side of the upper cushion block 120 away from the upper die base 110, the punching rod 140 is fixedly installed at a side of the punching fixed seat 130 away from the upper cushion block 120, the punching recess 150 is located at a side of the punching fixed seat 130 away from the upper cushion block 120, the stripping plate 160 is built in the punching recess 150 and the stripping rod 170 passes through the upper die base 110, the upper cushion block 120 and the punching fixed seat 130 in sequence from top to bottom and then is connected to the stripping plate 160;

[0025] The lower module 200 includes a lower die base 210, a lower cushion block 220, a punching convex fixing seat 230, a punching convex 240, an elastic ring 250, a placement plate 260 and a plurality of fixing screws 270. The lower cushion block 220 is located at the top of the lower die base 210 and the punching convex fixing seat 230 is located at the side of the lower cushion block 220 away from the lower die base 210. The punching convex 240 and the elastic ring 250 are both located at the The punching protrusion fixing seat 230 is away from the side of the lower pad 220 and the elastic ring 250 surrounds the punching protrusion 240, and the placement plate 260 is located on the side of the elastic ring 250 away from the punching protrusion fixing seat 230; the fixing screw 270 passes through the lower die seat 210, the lower pad 220, the punching protrusion fixing seat 230 and the elastic ring 250 from bottom to top in sequence and is then installed on the placement plate 260.

[0026] Specifically, the first guide rod 300 and the second guide rod 400 are installed between the upper die base 110 and the lower die base 210 .

[0027] More specifically, the punching protrusion 240 , the lower pad 220 and the lower die base 210 are all provided with corresponding discharge holes 241 .

[0028] Furthermore, the bottom end of the punching recess 150 is lower than the bottom end of the stripper plate 160 , and the bottom end of the punching recess 150 and the bottom end of the stripper plate 160 form a placement area 151 .

[0030] The principle of the utility model is:

[0031] First, the substrate 500 is placed on the placement plate 260, and the punching is started, so that the upper module moves downward along the first guide rod and the second guide rod. When the punching concave part touches the placement plate, it continues to press downward, so that the placement plate presses the elastic ring and moves downward, and then the punching convex part protrudes relatively and enters the punching concave part to perform shape punching on the substrate. At the same time, when the upper module moves downward, the punching rod also moves downward to punch through holes on the substrate, and the composite film with the punched shape and through holes is located in the placement area, and the integrated punching of the shape and through holes is completed (the waste generated by the punching rod when punching through holes falls out from the discharge hole);

[0032] After punching, the upper module moves up, and the placement plate returns to its original position due to the restoring force of the elastic ring, and then drives the discharge rod to drive the discharge plate to move down, so that the discharge plate protrudes out of the punching recess, and finally the composite film located in the placement area is dropped.

[0033] It is worth mentioning that the technical features such as the composite membrane involved in this utility model patent application should be regarded as the prior art. The specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected by conventional methods in the field and should not be regarded as the inventive point of this utility model patent.
