[0031] According to the size and shape of the aluminum strip, an appropriate limit frame 401 is selected, and then the limit frame 401 is inserted into the positioning groove, and the opening of the locking groove is made to face the storage groove. Then the horizontal push rod 403 is started to drive the locking block 404 to move until a part of the locking block 404 is inserted into the locking groove, thereby fixing the limit frame 401 and further fixing the position of the aluminum strip.

[0032] Embodiment 2: Figure 1-5 As shown, an aluminum plate strip punching mechanism includes a workbench 1, a bracket 2 fixedly connected to the top of the workbench 1, and a collection box 5 arranged at the bottom of the workbench 1, and also includes a punching mechanism arranged on the top of the workbench 1, and a positioning mechanism plugged into the top of the workbench 1;
