Description

Technical Field

[0001] The invention relates to the field of automation equipment, and in particular to an automatic direction selection mechanism for valve feeding. Background Art

[0002] Before loading and assembling hardware workpieces, the valves need to be automatically loaded and oriented. The efficiency of manual orientation selection is very low. At this time, an automatic loading and orientation selection device is needed to perform the orientation selection work.

[0003] The traditional vibration plate is used to select the direction of the valve for feeding. Since multiple valves are placed in the vibration plate at the same time, collisions occur between the valves, the noise frequency is very high, and the noise has high penetration. When the noise test is carried out in a space of 20 to 30 square meters, the noise reaches about 110-120 decibels. At the same time, the valve is difficult to align during the whole row feeding process. Since the vibration plate is continuously selected during feeding, a valve may have to be reciprocated many times, and the success rate is very low. It is estimated that the success rate of the vibration plate is less than 20%. At the same time, the valve will cause wear during the continuous selection process, and it cannot adapt to the requirements of faster feeding. Summary of the invention
