The hinge of a foldable screen phone is its core component, responsible for connecting the inner and outer screens and ensuring that the screen is smooth when folded and unfolded. The hinge technology is complex, and different manufacturers use different designs and materials, which affects the durability and reliability of the phone and the flatness of the screen after folding.

[0003] At present, the hinges of foldable screen mobile phones mostly use hinge-type hinges and teardrop-type hinges. There are many hinge components of the two types, and the components are small in size. The hinge blanks need to be fine-processed by CNC equipment. Before fine-processing, in order to improve the hardness, toughness and wear resistance of the hinge components, the hinge blanks need to be heat-treated. Since the hinge components are small, random stacking makes the gaps between the blanks uneven, resulting in uneven heating of the internal and external blanks.

[0034] Working principle of the discharge mechanism 8: In the discharge preparation stage, the swing arm 82 is rotated to make the sliding arm 85 extend into the discharge box 2, and the shaft blank is sent into the conveying matrix tube 2 92 through the conveying groove 91 of the shaft blank conveying mechanism 9. Under the support of the support frame 93, after the bottom end of the conveying matrix tube 2 92 is connected with the top of the conveying matrix tube 1 86, the conveying matrix tube 2 92 tends to a vertical state. After the shaft blank enters the conveying matrix tube 1 86, during the rotation of the discharge box 2, the shaft blank in the conveying matrix tube 1 86 automatically falls onto the supporting chassis 4 on both sides of the partition cylinder 32.

The connecting platform 42 cooperates with the slide groove 35 to drive the bearing chassis 4 to rotate, and cooperates with the discharge mechanism 8 to perform the discharge work. The baffle 43 can prevent the shaft blank from moving due to inertia during the discharge of the bottom layer. The shaft blank is divided into multiple stacking areas through the multi-layer partition cylinder 32. In the heat treatment stage, the heat generated by the heating ring 15 passes through the vertical groove 51, the horizontal groove 34 and the gap between the blanks to heat the inner and outer layers of the shaft blanks. In the hot processing process, the driving mechanism 7 drives the discharge box 2 to rotate so that the internal blank is heated evenly.

[0043] When the present invention is implemented, at the discharge stage, the discharge mechanism 8 is moved to the working position, the conveying rectangular tube 1 86 and the conveying rectangular tube 2 92 are connected, and the rotating shaft blank conveying mechanism 9 delivers the rotating blank to the discharge mechanism 8. The blank is arranged on the supporting chassis 4 during the rotation process through the discharge mechanism 8, and the rotation of the discharge box 2 and the lifting of the functional cylinder 3 are driven by the driving mechanism 7.
