[0026] By setting guide rail 310 and guide groove to guide the moving wheel 113, the movement direction of the platform 120 is restricted to ensure that the platform 120 moves in the second direction.

[0027] The moving stage drive structure 320 is a conventional electric linear module. The moving stage drive structure 320 is fixedly installed on the factory floor. The output end of the moving stage drive structure 320 is fixed to the first moving stage 110.
