In the production process of label stickers, such as some trademark patterns and icon designs, it is usually necessary to punch holes in some hollow positions to form specific patterns, or as a positioning function in subsequent processing procedures.

Punching machine is a commonly used mechanical processing equipment for punching label stickers. During the process of using the punching machine, the worker needs to hold the label sticker and place it on the positioning mold of the punching machine, then press the start button, and the punch will descend to punch. In this process, it is inevitable that workers will not have a strong sense of safety, or there will be human errors. The worker's hand does not leave the positioning mold area when the punch is punching downward, which will cause personal injury to the worker and occur. security incident. Therefore, it is of great significance to add a safety protection device to the punch press to protect the personal safety of the worker in time when the worker does not operate properly.

Most of the existing punch protection devices use foreign object sensing or operating condition control to stop the movement of the punch when an abnormal situation occurs. However, this method has a certain hysteresis. For example, when the punch has fallen, it is difficult to offset Inertia, and the final effect depends on good electrical control conditions. When some circuit failures or electronic control failures occur, it is easy to fail; and this kind of protection method is not conducive to the development of good operating habits of workers.
