[0022] During use, the vibrating disk 1 conveys the spring to the opening on the material transfer platform 201. A discharge portion 203 is provided at the bottom of the opening to support the spring in the opening and prevent it from falling. When the cylinder corresponding to the discharge portion 203 adjusts its retraction, the discharge portion 203 moves away from the bottom of the opening. At this time, the corresponding cylinder adjusts the discharge portion 202 to move downward, and the discharge portion 202 pushes the spring in the opening out, and the spring falls downward.

[0023] Refer to Figure 3 As shown, the device also includes a transfer mechanism 3, which is composed of a cylinder and a receiving platform 301. The receiving platform 301 is provided with an inclined channel. The receiving platform 301 is arranged below the material transfer platform 201. The channel on the receiving platform 301 receives a spring falling from the opening of the material transfer platform 201, and the position of the receiving platform 301 is adjusted by the cylinder.

[0024] During use, the fallen spring falls into the channel on the receiving platform 301. After the sensor detects the spring, it controls the receiving platform 301 to move toward the pressing mechanism 4 through the corresponding cylinder.
