In the existing screw cutting mechanism in the market, the screw cutting and blowing are carried out at two different positions, the screw is moved into a screw blowing hole at the other position after the screw cutting is finished, and then the screw is blown; the moving distance of the screw is large, and meanwhile, the split position is a screw head, so that for a long screw, the screw is easy to deflect in the rapid screw splitting process and cannot smoothly fall into a screw blowing hole; for thin-headed screws, jamming of the screw head at the gap between the cut parts is likely to occur. The cutting block of the screw is in a block design and is usually connected to the tail end of a vibration disc, due to vibration, the posture of the screw is not vertical, the cutting block in the block design is easy to extrude the screw in the rapid moving process, and the phenomenon of staple is caused. Therefore, the nail cutting speed and efficiency cannot be improved. In summary, these approaches have several major disadvantages:
1. the screw displacement is large in the screw cutting process, and the screw cutting efficiency is low;
2. the cutting driving position is a screw head, and the long screw is easy to be skewed during cutting;
3. the cutting driving position is a screw head, and the clamping stagnation of the screw head at the gap of a cutting part is easy to occur during the cutting of the thin-head screw;
4. the nail cutting block is easy to extrude the screw, and the phenomenon of nail clamping occurs.
In summary, for the automated assembly of a large number of screws, a screw cutting and outputting integrated mechanism with a special structure is particularly needed to solve the problem, so as to further improve the assembly quality of the product.
