[0002] Traditional machine tool processing is all achieved by manual loading and unloading. Later, in order to reduce labor costs and improve production efficiency, many mechanisms for loading and unloading machines have emerged. However, an existing loading and unloading mechanism that can be used for two CNC machine tools at the same time, although the guide rail of the material transfer module is appropriately extended, and the loading and unloading modules are arranged at the center of the transverse guide rail, and a first placement position and a second placement position are formed for placing the CNC machine tools, so that the loading and unloading of the two CNC machine tools can be achieved; at the same time, the loading and unloading modules are arranged between the two CNC machine tools, which can well take into account the loading and unloading efficiency, but it is impossible to load and unload multiple CNC machine tools at the same time, and loading and unloading operations need to be performed separately, especially when the adjacent CNC machine tools are of different sizes, it is even more impossible to realize the function of loading and unloading multiple CNC machine tools at the same time, so there is a problem of low loading and unloading efficiency.

[0004] However, in the implementation of relevant technologies, it was found that the loading and unloading mechanism of the above-mentioned design that can be used for two CNC machine tools at the same time has the following problems: although the guide rail of the material transfer module is appropriately extended, and the loading module and the unloading module are arranged at the center of the transverse guide rail, and a first placement position and a second placement position are formed for placing the CNC machine tools, thereby realizing loading and unloading of the two CNC machine tools; at the same time, the loading module and the unloading module are arranged between the two CNC machine tools, which can well take into account the loading efficiency and the unloading efficiency, but it is impossible to load and unload multiple CNC machine tools at the same time, and the loading and unloading operations need to be performed separately. In particular, when the adjacent CNC machine tools are of different sizes, it is even more impossible to realize the function of loading and unloading multiple CNC machine tools at the same time. Therefore, there is a problem of low loading and unloading efficiency. In view of this, a loading and unloading device for multiple CNC machine tools is provided to overcome the above-mentioned defects. Utility Model Content
