Description

TECHNICAL FIELD

[0001] The utility model belongs to the round stick processing technical field, concretely is a kind of round stick product automatic feeding system. BACKGROUND

[0002] Germanium is an important semiconductor material, often used in electronic and optoelectronic devices. Germanium is an ideal material for infrared detectors due to its unique optical properties, making it an important material in high-frequency devices and infrared optics. In addition, germanium metal is off-white, brittle, and highly stable in air at room temperature, maintaining its original beautiful luster.

[0003] CN202223362644.4 discloses a jacking and distributing mechanism, including a fixed seat, a track with an inlet end and an outlet end, a distributing seat at the outlet end, a positioning block with a receiving groove, a first inclined surface and a blocking surface, a material lifting rod with a second inclined surface and a driving assembly at the end of the distributing seat.

[0004] In the above technical solution, the material lifting rod lifts the bar at the outlet end and makes it higher than the height of the blocking surface. The bar rolls along the second inclined surface and the first inclined surface, and then falls along the first inclined surface into the receiving groove, achieving the distribution of the bar to be clamped from the remaining bars. The material is taken out of the receiving groove by a mechanical hand, preventing the bar from piling up and achieving precise material taking. However, when the bar rolls along the inclined surface, it has a large inertia. Since the round bar made of germanium material is very brittle, it is easy to break when the bar rolls into the receiving groove. Utility model content

The power output end of the lifting unit 2 is provided with a receiving portion 24 for carrying round bars. The feeding unit 1 conveys the round bars one by one along the inclined direction of the inclined surface 121 into the receiving portion 24 through a conveying inclined surface 121.

[0036] When the round rod is placed in the receiving portion 24, the lifting unit 2 drives the receiving portion 24 upward to lift the round rod;

[0037] The clamping and feeding unit 3 is used to grab the lifted round rod and transfer it to the next workstation.

[0038] Under this design, the round rods are transported one by one to the accommodating portion 24 of the lifting unit 2 through the inclined surface 121 of the feeding unit 1. When the round rods are located in the accommodating portion 24, the lifting unit 2 drives the accommodating portion 24 to rise to lift the round rods in the accommodating portion 24. After the round rods are lifted, the clamping feeding unit 3 grabs the round rods in the accommodating portion 24 and transfers them to the next workstation. In this way, damage to the round rods is reduced and the round rods are avoided from being broken during the sliding process.
