Specifically, as shown in fig. 3 to 5, the feeding mechanism 24 includes at least three positioning assemblies 241, each positioning assembly 241 includes a positioning block 242 and a positioning rod 243 installed on the positioning block 242, the positioning block 242 is installed on the turntable 22, a positioning groove (not labeled in the drawings) for loading the product 5 to be punched is formed between at least three positioning blocks 242, and the positioning rod 243 is used for preventing the product 5 to be punched from falling after the product 5 to be punched is stacked in the positioning groove. According to the invention, the feeding mechanism 24 is composed of four positioning components 241 and is used for enclosing to form a positioning groove, so that the feeding robot 3 can accurately pick up the product 5 to be punched without shaking after the product 5 to be punched is fed; meanwhile, the positioning rod 243 is arranged to ensure the stability of the stacked products 5 to be stamped. Of course, the reason why the four positioning components 241 are adopted to form the feeding mechanism 24 is that the watch is generally provided with four watch ears, and four hole positions are respectively formed between the four positioning components 241 to be matched with the four watch ears, so that the positioning is more stable.

Preferably, as shown in fig. 5 and 6, the positioning assembly 241 further includes a positioning screw (not shown), the positioning block 242 is provided with an adjusting groove 244, the rotary plate 22 is provided with a positioning hole 221, and the positioning screw passes through the adjusting groove 244 and then is screwed into the positioning hole 221, so as to connect the positioning block 242 and the rotary plate 22.
