Description

Rain plug feeding device and method Technical Field The invention relates to the technical field of intelligent wire harness processing, in particular to a rain plug feeding device and method. Background The rain plug is a key sealing component in the intelligent wire harness system, is usually assembled at the tail part of a wire harness connector or a through hole penetrating through a metal plate of a vehicle body, and mainly plays roles of water resistance, dust resistance and vibration resistance. With the development of automobile electronics and intelligent driving technology, the integration level of the wire harness is higher and higher, and stricter requirements are also put forward on the assembly precision of the rain plug. Currently, many high performance rain plugs are designed to be asymmetric in order to meet specific installation orientation and sealing performance requirements, and must be installed with certain features oriented in certain directions that would otherwise lead to seal failure or even connector failure. The rain plug fed by the application comprises a plurality of layers of sealing lips which are annularly arranged, a groove is arranged between every two adjacent sealing lips, a chamfer is arranged on one side of the sealing lips facing the installation direction, one side of the sealing lips far away from the installation direction is a plane, and a threading hole is arranged in the center of the rain plug. In the prior art, the feeding of the rain plugs is generally carried out by adopting a mode of matching a vibration disc with a direct vibration track, and the feeding device can only realize continuous feeding of materials and can not automatically identify and screen the directions in the feeding process. Because of the small volume and similar appearance of the wiper plug, fine directional features are difficult to distinguish by simple mechanical blocking or gravity screening. Once the rain plugs with wrong directions enter the assembly process, the rain plugs can directly cause equipment material clamping and stopping, even crush products, and seriously influence the continuous operation rate and the product quality of the production line. Therefore, there is a need for an efficient feeder device capable of identifying and automatically screening the direction of a rain plug on line, so as to solve the problem that the prior art relies on manual or high-cost visual equipment due to random direction of the rain plug. The front and back characteristics of the rain plugs are accurately distinguished, materials with qualified directions are sequentially conveyed to the assembly station, meanwhile, the materials with unqualified directions are automatically removed or adjusted, so that intelligent feeding with full automation, high efficiency and high stability is realized, and the intelligent level and the product yield of a wire harness production line are further improved.
