[0031] Furthermore, as a preferred embodiment, the feeding device 5 includes: a fixed bracket 51, a belt 52, a rotating shaft, and a motor mounting plate 53.

[0036] Furthermore, as a preferred embodiment, the pin blank forming equipment 1, the pin blank processing equipment 4, and the robot joint 22 are all existing technologies, and therefore will not be described in detail here.

[0037] The working principle of this utility model is as follows: In use, plastic particles are first manually added to the pin blank forming equipment 1. Then, the pin blank forming equipment 1 heats the plastic particles and automatically stretches and shapes them to obtain the pin blank. Subsequently, the control system 3 sends instructions to the automatic loading and unloading robot 2. The robot joint 22 of the automatic loading and unloading robot 2 rotates according to the instructions of the control system 3. When the robot joint 22 is adjusted to a suitable angle and position, the cylinder 23 extends to lower the electric gripper 25 to a suitable height. Then, the motor assembly 252 of the electric gripper 25 drives the drive component to move. The movement of the drive component causes the two sliders 254 to slide away from each other on the gripper guide plate 253, thereby causing the two gripping fingers 255 to open and grasp the pin blank. Then, the motor assembly 252 of the electric gripper 25 again drives the drive component to move, causing the two sliders 254 to slide away from each other on the gripper guide plate 253. 4. The two grippers 255 slide towards each other on the gripper guide plate 253, so that they come closer together to grip the pin blank. After gripping, the cylinder 23 retracts to raise the electric gripper 25 to a certain height. The robot joint 22 is then adjusted to a suitable angle and position to transport the gripped pin blank to the processing station of the pin blank processing equipment 4. The pin blank processing equipment 4 can perform precise processing on the pin blank according to the pre-written processing program. After processing, the control system 3 sends an instruction to the automatic loading and unloading robot 2. The automatic loading and unloading robot 2 repeats the above operation to transport the processed pin from the pin blank processing equipment 4 to the belt 52 of the unloading device 5. The motor on the motor mounting plate 53 of the unloading device 5 can drive the rotating shaft to rotate, thereby driving the belt 52 to run. After the automatic loading and unloading robot 2 places the pin on the belt 52, the pin can be transported in an orderly manner with the movement of the belt 52, thus completing the unloading process.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
