[0002] The school's teaching curriculum includes practical courses, and students' practical courses will use simulated practical tools. The simulated tools used in students' practical courses are generally designed in a modular manner to facilitate assembly in practical classes. Modular practical simulation tools use automated assembly equipment in the factory to perform assembly operations between parts, and use automated assembly robotic arms to move parts on the conveying mechanism to the assembly platform, and place multiple parts in designated positions in turn before performing assembly operations. Modular practical simulation tools have a combination of plate-shaped parts and fan-shaped parts. When automated assembly robotic arms are used to perform assembly operations on plate-shaped parts and fan-shaped parts, the fan-shaped parts conveyed to the position of the robotic arm are not completely in the specified installation state.

The first profiling clamping frame (31) and the second profiling clamping frame (32) contact the fan-shaped part from the left and right sides of the fan-shaped part respectively. The first profiling clamping frame (31) and the second profiling clamping frame (32) gradually close the mold to position the fan-shaped part on the top of the plate-shaped part. S3, the other two assembly robot arms (12) operate to operate the threaded connectors to complete the assembly of the fan-shaped parts and the plate-shaped parts; S4. After the parts are assembled, the driving motor (42) operates to separate the first contour card frame (31) and the second contour card frame (32) from the outside of the fan-shaped parts, and the assembly robot arm (12) on the right side operates to remove the assembled modular parts from the assembly area on the top of the parts assembly table (11) and move them to the external conveying mechanism for further transportation.
