However, the output length of the existing connecting wire is usually fixed and difficult to adjust according to actual needs, which limits its applicability and flexibility in different scenarios. In addition, the current connection method between the linear motor mover and the stator device is single, and it is difficult to flexibly switch between multiple stator devices, which limits the application range and efficiency of the linear motor system.

[0035] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

Preferably, at least two groups of linear motor stator devices 1 and two groups of first linear moving mechanisms 2 are arranged on a bracket 5 to improve the integrity of the connecting wire;

[0037] One output end of one set of the first linear moving mechanisms 2 is connected to one end of all the linear motor stator devices 1, and the output end of the other set of the first linear moving mechanisms 2 is connected to the other end of all the linear motor stator devices 1. Preferably, multiple sets of linear motor stator devices 1 are parallel to each other and in a linear structure, and the two sets of the first linear moving mechanisms 2 are also parallel to each other and in a linear structure. That is, when two sets of linear motor stator devices 1 are provided, the two sets of the first linear moving mechanisms 2 are connected end to end to form a "square" - shaped structure, and the two sets of the first linear moving mechanisms 2 are arranged oppositely, and the two sets of linear motor stator devices 1 are arranged oppositely.

[0039] One set of the linear motor stator devices 1 is formed by connecting several linear motor stator modules 11 in series, which is convenient for adjusting the length of the linear motor stator device 1 and simplifies the installation of the linear motor stator device 1. A linear motor stator module 11 is provided on the output end of the first linear moving mechanism 2, which is convenient for the linear motor mover 3 to actively enter or leave the output end of the first linear moving mechanism 2.

[0043] The two magnets 32 correspond to the electric excitation magnetic field generating component 112. That is, by controlling the voltage and current output to the electric excitation magnetic field generating component 112, the movement of the linear motor mover 3 can be controlled. In this embodiment, the linear motor mover 3 can be made to move at a constant speed or a variable speed by controlling the electric excitation magnetic field generating component 112.
