[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the spring feeding assembly of the present invention is working, the cover on the top plate is opened, the spring is placed in, and then the cover on the top plate is closed. At this time, except for the air inlet hole on the feeding blowing block A and the air outlet hole of the feeding blowing block C, the spring feeding assembly forms a closed space; the gas entering through the air inlet hole of the feeding blowing block A blows the spring on the top plate clockwise along the bottom of the arc plate and falls on the feeding blowing block B; the spring that does not fall into the semicircular groove is blown back and falls on the top plate, and the spring that falls into the semicircular groove above the feeding blowing block B is blown back and falls on the top plate in the spring feeding assembly The gas enters the air inlet on the inner feeding and blowing block A and is blown out through the semicircular groove on the feeding and blowing block B, the spring discharge hole, and the discharge holes on the upper and lower sides of the feeding and blowing block C, thereby forming a negative pressure at the spring discharge hole. The positive pressure is formed inside the cavity of the spring feeding assembly and blown toward the spring feeding hole, causing the spring falling into the semicircular groove to be blown toward the spring feeding hole and enter the nylon tube through the feeding and blowing block C to send the spring out. After the spring is sent out horizontally, under the action of gas and gravity, the spring is sent vertically through the nylon tube to the sub-spring dispensing assembly below. The spring feeding assembly can adjust the speed and quality of the spring delivery by controlling the air intake of the feeding and blowing block A, the exhaust times, pressure and beat of the feeding and blowing block C, and does not adopt the existing vibrating plate feeding method, with small size and low noise.

[0015] 2. When the spring dividing assembly of the present invention is working, after the spring in the nylon tube enters the feeding trough, the upper dividing cylinder extends out, and the upper dividing cylinder drives the ejector on the upper ejector seat to be pulled out, and all the springs fall along the feeding trough until the first spring is blocked by the ejector on the lower ejector seat. At this time, after the spring sensor detects the spring, the upper dividing cylinder retracts, and the upper dividing cylinder drives the ejector on the upper ejector seat to insert into the middle part of the second spring, and the second spring is fixed. Then, the lower dividing cylinder retracts, and the lower dividing cylinder drives the ejector on the lower ejector seat to retract, and the first spring is sent away along the trough under the action of gravity and gas. At this time, after the spring sensor does not detect the spring, the lower dividing cylinder extends out, and the lower dividing cylinder drives the ejector on the lower ejector seat to extend out, and the upper dividing cylinder extends out, and the upper dividing cylinder drives the ejector on the upper ejector seat to be pulled out, and all the springs fall along the feeding trough until the first spring is blocked by the ejector on the lower ejector seat. Repeat the above method to accurately send the springs to the required positions one by one.
