Technical Field

[0001] This utility model relates to the field of push mechanism, and in particular to a PIN pin precise positioning push mechanism. Background Technology

[0002] Pins, also known as leads or terminals, are the parts on electronic components used to connect to external circuitry. They allow current to pass through and are essential for ensuring that a device is properly connected to other components or circuit boards. In the electronics manufacturing process, it is common practice to embed pins into the mold, especially during injection molding. By embedding part or all of the pins into the plastic part, the mechanical strength of the connection point can be increased, making the final product more robust and durable.

[0003] When PIN pins are embedded in the mold, a vibratory feeder is usually used for feeding. However, the positioning accuracy of the vibratory feeder is insufficient, and the PIN pins often need to be manually grasped to assist in embedding them into the mold. This method has a low degree of automation and can easily affect work efficiency. Alternatively, a robot can be used for grasping, but this is more expensive and less practical.

One position detector is located above the vertical vibrator, while the other position detector is located at the front end of the top material cylinder. The position detector is a reflective photoelectric sensor.
