Description

Directional alignment feeding device for relay assembly Technical Field The invention belongs to the technical field of electronic component manufacturing and assembly, and particularly relates to a feeding device for assisting miniature contact elements to conduct batch directional alignment in a relay or Printed Circuit Board (PCB) assembly production process. Background In the automated assembly process of precise electronic components such as relays, micro switches and the like, the feeding and feeding of contact elements is a key pre-process. Relay contacts generally have an asymmetric physical structure, one side being a soldering plane (non-assembly plane for suction) and the other side being a working convex plane (assembly plane, functional side). In the SMT mounting or mechanical arm assembling link, the assembling equipment (such as a mounting machine) requires that the incoming materials must be unified into a 'plane upwards' posture, so that the vacuum suction nozzle can be used for stably sucking and transplanting. In the current state of the art, the feeding of such miniature asymmetric elements relies mainly on vibrating discs. However, for the specific object of relay contacts, the conventional vibrating tray feed has the following significant pain points: The feeding posture is unstable, so that the suction failure is caused, the vibration plate is screened by virtue of a track, the screening yield is difficult to reach 100% for miniature contacts with extremely small gravity center difference, and reverse materials are mixed frequently, so that the suction nozzle of the assembling machine is blocked or the machine is stopped for throwing materials. Surface damage affects electrical performance, and long-distance screw transport of the vibrating disk can cause severe friction between contacts and rails. The surface of the relay contact is usually plated with a soft silver layer, which is very easy to scratch in conveying and seriously affects the contact resistance and the electrical life of the finished product. Static electricity and greasy dirt adhesion, namely that the miniature sheet metal element is extremely easy to be adsorbed on a conveying track due to surface Van der Waals force or static electricity, so that feeding is blocked, and the beat of a production line is influenced. Therefore, there is a need for a dedicated feeder that can replace the conventional vibration plate, utilize discrete microstructures for batch alignment, and output efficiently and nondestructively in a vacuum suction position.
