This technical background provides a solid foundation for the precise control of planar motion structure.

[0003] However, in some existing planar motion structures, although PLC and servo control technology provide precise control means, there are still many challenges in achieving the free movement of objects in the X and Y axis directions. Because driving force needs to be applied in both directions, larger equipment needs to move with heavy motors, which not only increases the overall load of the system, reduces the running efficiency, but also puts higher requirements on the stability and reliability of the equipment. At the same time, the movement of the motor requires the use of auxiliary equipment such as drag chains to protect the wires, but phenomena such as wire sheath wear, equipment failure, and electrical leakage are still difficult to avoid. In addition, the complexity of this structure makes the installation and maintenance process very cumbersome, and when the equipment is upgraded, especially when the driving force is upgraded, resulting in a change in the size of the motor, often requires the replacement of a large number of accessories, or even cannot be upgraded due to the weight of the motor, limiting the flexibility and scalability of the equipment.

[0005] In the above patent disclosed plane movement structure, the movement of the moving block depends on the change of the direction of the rotation of the first screw rod by the driving device to realize the movement of the moving block in the X-axis direction or in the Y-axis direction, but cannot realize the synchronous movement in the X-axis and Y-axis, which will slow down the movement stroke and speed, and the efficiency is not high, so now a kind of movement control mechanism with simple structure and realizing the movement in X-axis and Y-axis separately or simultaneously is needed.
