[0022] The present utility model will be further described below in conjunction with the accompanying drawings of the specification, but the present utility model is not limited to the following embodiments.

[0023] Embodiment 1

[0024] An edge skin detection mechanism, as Figure 1 - Figure 2 shown, the edge skin detection mechanism is arranged on the fixed connecting plate. The edge skin detection mechanism includes a guiding shaft 1, the guiding shaft 1 penetrates through the fixed connecting plate, a bearing 3 is sleeved on the outer periphery of the guiding shaft 1, a spring 2 is sleeved on the lower part of the guiding shaft 1, fixing rings 4 are sleeved on the bottom and top of the guiding shaft 1, an induction ring 6 is arranged at the top of the guiding shaft 1, and a detection limit position switch 8 and a detection of workpiece presence / absence switch 9 are respectively arranged at adjacent positions of the induction ring 6; the bottom end of the guiding shaft 1 is connected to a positioning block 5.
