The four grassroots stages of the electronic connector manufacturing process

1. Stamping: The manufacturing process of electronic connectors generally starts with the stamping of pins. Through a large high-speed stamping machine, electronic connectors (pins) are stamped from thin metal tape. One end of the large roll of metal tape into the front of the press, the other end through the hydraulic press table wrapped into the tape wheel, the tape wheel pulls out the metal tape and rolled stamping out the finished product. 2. plating: connector pin stamping is completed that should be sent to the electroplating on the section. In this stage, the connector electronic contact surface will be plated with a variety of metal coatings. With the stamping stage similar to a class of problems, such as pin distortion, broken or deformation will also be the same in the press good pins into the electroplating equipment in the process, this kind of quality defects are easy to be detected. 3. injection molding: electronic connectivity plastic box seat in the injection molding stage is made, the usual process is to melt the plastic injected into the metal tire film, and then quickly cooled and shaped. When the molten plastic does not completely fill the tire membrane, this is a typical defect to be detected during the injection molding stage. Other defects include filled or partially clogged sockets (which must be kept clean and clear in order to be properly connected to the pins during final assembly). Because of the use of backlighting can easily recognize the box seat leakage and connecting holes plugged cold, so the dry injection molding after the completion of the quality inspection of the machine vision system is relatively simple and easy to implement. 4. assembly: the final stage of electronic connector manufacturing is the assembly of finished products, will be plated pins with the injection molding box seat connected to the plug there are two kinds of ways: alone or a combination of pairs of plugs, alone refers to each time to connect and insert a pin: combination of pairs of pairs of plugs at one time will be Multiple pins are connected with the box seat at the same time. Regardless of which way of insertion, the manufacturer is required to detect all the pins in the assembly stage whether there is a lack of session and positioning of the correct; another category of routine inspection of the service is related to the connector mating surface pitch measurement, and stamping stage, the assembly of the connector is also the challenge of the automatic inspection system in the detection of the speed. Although most assembly lines run at one or two pieces per second, the vision system usually has to perform several different inspection tasks for each connector that passes through the camera. Inspection speed is once again an important system performance metric.
