[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figure 1 and Figure 2 , Figure 1In the prior art PCB punching inner hole processing device 1, before punching the inner hole 101, a positioning hole needs to be punched out for positioning the sheet material 100. The specific process is: the punching material 11e is pre-made with a positioning hole, and then the punching material 11e is placed in the lower template 1d and positioned by the positioning pin 11f as a pad for the sheet material 100 to avoid burrs caused by punching and affecting the flatness of the sheet material 100. Put the sheet 100 for punching. When the upper template 1a moves downward, the mold guide column 11a enters the mold guide sleeve 11g, and the positioning pin 11f extends into the positioning groove 11d. The stripper plate 1b will press the sheet 100 and the punching material 11e, and continue to move downward. The mold stripper spring 11b will be compressed, and the stripper plate 1b rises. The mold punch 11c exposed from the rising stripper plate 1b enters the concave template 1c to press the sheet 100 and the punching material 11e and completely shear it off. The waste material falls from the bottom of the lower template 1d, and the inner hole 101 is punched out. The upper template 1a moves upward again, and the mold stripper spring 11b will restore the compression amount. The sheet 100 relies on the stripper plate 1b to remove the waste material. Finally, the sheet 100 falls on the lower template 1d, completing a step of punching process.

[0032] See also Figure 3 and Figure 4 , Figure 3 The device 2 for punching graphic shape processing of a PCB board in the prior art is used to place a sheet material 100 having an inner hole formed by punching an inner hole on a punching material 23a in a lower template 2d, wherein a positioning hole of the sheet material 100 having an inner hole formed by punching an inner hole cooperates with a positioning pin 23b to fix the sheet material 100 having an inner hole formed by punching an inner hole and the punching material 23a serving as a pad. During punching, when the upper template 2a moves downward, the mold guide column 21b enters the mold guide sleeve 23c, and continues to move downward. The positioning pin 23b extends into the positioning groove 22a, and the stripper plate 2b will press the punching material 23a. The mold stripper spring 21c and the compression spring 24b in the cavity 24a of the lower template 2d will be compressed synchronously. At this time, the stripper plate 2b rises, and the stripper block 23d under the punching material 23a will drop. The mold punch 21a enters the concave template 2c to completely shear the punching material 23a and the sheet material 100. At this time, a graphic 102 containing an inner hole 101 is obtained. At this time, the upper template 2a moves upward again, and the mold stripping spring 21c and the compression spring 24b will restore the compression amount, and the waste material 23a and the sheet material 100 will be removed from the mold punch 21a by the stripping plate 2b, and the stripping block 23d will remove the finished product of the pattern 102 containing the inner hole 101 from the lower template 2d, and finally the punching material 23a and the sheet material 100 will fall on the lower template 2d.

[0033] The above two punching devices use two sets of molds to punch twice to complete, and require two positionings. However, in this embodiment, the above two punching steps are completed once with one set of molds. The inner hole 101 and the figure 102 are punched out at the same time, saving punching time and improving the accuracy from the inner hole to the outer edge.
