The first Y-axis drive module 31 controls the front and rear positions of the workpiece and, according to the processing steps required for the workpiece, moves it to the corresponding hole processing component 42 position in the drilling mechanism 4. The workpiece is processed by component 42. After one process is completed, it is transferred to the next hole processing component 42 for further processing until the processing is completed. Then, the first Y-axis drive module 31 controls the clamping fixture 32 to move backward to above the unloading box 24. The unloading component 324 pushes out the processed workpiece. After the material falls, it is collected and guided by the unloading box 24.

This design can efficiently complete the automatic positioning of the product and multiple hole processing processes, greatly improving work efficiency.
